Fish tape, also known as draw wire or draw tape, is an essential tool
used by electricians and network installers across the globe due to its
simplicity and utility. In a nutshell, it’s a long, thin metal strip,
often made of steel or sometimes fiberglass, which is wound inside a
compact, handheld reel. This tool’s main purpose is to guide electrical
wiring and cables through tight spaces, such as conduits or hollow
walls, facilitating the process of creating or improving electrical or
network lines within buildings. Despite its peculiar name, it has
nothing to do with fish; rather, the term ‘fish’ is used in the sense of
catching or retrieving something, in this case, wires.
The Importance of a Fish
Tape
Usage in
electrical or network installations
Fish tape is an indispensable tool in the arsenal of electricians and
professionals dealing with network installations. It is primarily used
to route new wiring through walls and electrical conduit due to its
flexibility and strength.
The process of installing new electrical lines or network cables
involves stringing them through previously installed conduits or
directly inside walls. However, manually feeding these wires can become
a labor-intensive and challenging task, more so when the conduits have
bends or participants need to carefully avoid other sensitive
installations such as water pipes or previously installed wires.
That’s where fish tape excels. Due to its flat, narrow profile and
flexibility, it can easily navigate the tightest of corners and the most
congested of conduits. Electricians and network installers attach the
end of the electric wire or network cable to the fish tape, route it
through the desired path, and then pull it out from the other end,
effectively threading the wire or cable through the conduit or wall.
This tool significantly simplifies challenging tasks, reduces the
time and effort involved, and increases the efficiency and productivity
of electrical or network cabling projects. Fish tape is, therefore,
deemed nearly invaluable in such installations because of its
effectiveness and the labor savings it offers.
Efficiency in
pulling wire through a conduit
Fish Tape plays a significant role in providing an efficient solution
for pulling wires or cables through conduits, conduit pipes, tight
spaces, narrow ducts or channels. Navigating wires through these
restricted areas can be a daunting task, but Fish Tape simplifies this
operation substantially.
Unlike other methods, Fish Tape enables a worker to pull wires
through a conduit with relative ease. It takes less time, less human
effort, and can significantly reduce the amount of manual labor
involved. This efficiency provides a boost in productivity, especially
in more substantial projects where time is of the essence.
The design of the Fish Tape, more often than not, allows it to
seamlessly glide through bends, making it incredibly useful in cases
where the conduit has multiple angles. Moreover, it can pull multiple
wires at a time, thus lowering the time spent on the task and increasing
efficiency.
In complex construction or wiring projects, the significance of this
efficiency cannot be overstated. It makes for faster project completion,
saves energy, and ensures that the wiring process does not become a
bottleneck in the entire operation. Therefore, the efficiency of Fish
Tape in pulling wires through a conduit cements its position as an
indispensable tool in electrical or network installations.
The Mechanism of a Fish Tape
Made of Flexible Steel
Fish tape is primarily composed of a flexible steel material that is
specially designed to bend and twist through tight spaces without
breaking or losing its shape. This malleability allows it to traverse
complex pathways inside walls, over ceilings, under carpets, or even
through conduit tubing. The steel used in the manufacturing process is
sturdy enough to withstand the friction and resistance it encounters
during use. Despite its durability, the steel retains an impressive
extent of flexibility — this critical balance between strength and
adaptability is what makes fish tape such an indispensable tool for
electricians and network installers.
Encased in a Plastic Reeled
Case
Fish tapes are typically housed in a sturdy plastic case that is
designed to be easy to grip and withstand the wear and tear of being
used on job sites. The reel inside this case is used for both storage
and deployment of the actual tape. When the fish tape is not in use, the
user can simply wind it up onto the reel, keeping it clean, unknotted
and safe from damage.
The plastic reel case also provides a method of deploying the fish
tape into and out of the conduit. When deploying, the user rotates the
reel, allowing the fish tape to extend out of the case and into the
conduit. During retrieval, the user can quickly reel the tape back into
the case, keeping their work area tidy and ensuring the tape is ready
for the next use.
Not only does the plastic reeled case enhance the overall efficiency
and user-friendliness of the fish tape tool, but it also significantly
contributes to the tool’s longevity. Therefore, the presence of a reel
case is a fundamental feature in a fish tape that every potential user
should look for.
Overview of its
functionality
A fish tape is essentially a long, thin strip of flexible metal rod
or wire, usually wound up in a donut-shaped plastic reel for easy
deployment and storage. The functionality of this device can be compared
to fishing, hence the name – where a thin piece of line is sent down a
path to retrieve something, just as a fisherman casts his line to catch
a fish.
In terms of a fish tape’s functionality, the process begins when the
flat, coiled metal tape is pushed down a conduit, a specific enclosed
route designed for cables or wiring, until it reaches the end. Remember
that fish tape is meant to be flexible to facilitate maneuvering around
corners or bends within these conduits.
Once the tip of the fish tape emerges at the end of the conduit, a
cable or wire can be securely attached to it. The fish tape is then
pulled back through the conduit, and in the process, pulls the attached
wire or cable along with it. This method simplifies the procedure of
threading a wire or cable through a long and potentially winding
conduit, something that would be difficult, if not impossible, to
achieve by merely trying to push the wire through.
Finally, once the wire or cable has been threaded through to the
desired length, it can be detached from the fish tape, which can be
wound back onto its reel for next use. In a nutshell, that’s how the
humble, yet immensely useful, fish tape functions.
Types of Fish Tape
Metallic Fish Tape
Metallic fish tapes, as the name implies, are made from various types
of metal. The most common variant is constructed from spring steel due
to its flexible yet sturdy properties. This type of fish tape is known
for its superior strength and durability. It’s designed to withstand a
great deal of force and is perfect for long runs through bends and turns
in the conduit. In most cases, the tape is flat and coiled inside a
dispenser that also has a handle for easy winding and unwinding. One
thing to keep in mind, however, is that metallic fish tape conducts
electricity, so extra caution is needed when working around live
circuits.
Non-Metallic Fish Tape
Non-metallic fish tape, as the name suggests, is a variant that isn’t
made from metal materials. Constructed from materials like fiberglass or
nylon, these fish tapes are valued for their flexibility, strength, and
non-conductive properties. Ideal for longer runs and particularly
beneficial in live environments, non-metallic fish tape is a safer
choice as it reduces the risk of shorting or electric shock. It is often
encased in a low-friction, high-impact plastic casing which also makes
rewinding easier. However, while this type does offer advantages such as
being lighter and safer, it may not be as robust as metal fish tape and
might not withstand the demands of very heavy duty tasks or particularly
harsh environments.
How to Use a Fish Tape
Steps involved in using Fish
Tape
Using a fish tape to thread cables may seem intimidating at first,
but with these step-by-step instructions, the process becomes
straightforward.
- First, ensure the conduit is clear, accessible, and free of sharp
edges that could damage the fish tape or wire. - Next, prepare the fish tape by pulling out the necessary length
to reach the opposite end of the conduit. - Carefully insert the fish tape into the conduit. If you are
pulling wire through a pipe with several bends, avoid pushing the tape
too quickly. Rather, allow the flexibility of the fish tape to navigate
through the curves gently. - Continue pushing the fish tape through the conduit until it
emerges at the opposite end. - Once the fish tape is through, the wire or cable you want to
install needs to be attached. This is usually done by creating a compact
hook on the wire, attaching it to the hook at the end of the fish tape,
and then securing it with electrical tape to ensure a snug fit. - With the wire or cable securely attached, begin to reel in the
fish tape back through the conduit, pulling the wire along with it.
Always maintain a steady and controlled pull to prevent damaging the
wire or getting it stuck. - Finally, once the cable has emerged from the conduit, disconnect
it from the fish tape. Before you put away the fish tape, ensure that
it’s properly coiled back into its case to avoid subsequent use
difficulties and potential injury.
Remember that patience is crucial while using fish tape. Avoid
forcing it through the conduit; let its flexibility do the work,
especially when navigating through bends and narrow parts.
Potential risk and safety
measures
Using a Fish Tape isn’t overly complex, but it does carry a number of
potential risks that users should be aware of. For starters, since Fish
Tapes are often used in electrical installations, there’s a risk of
electric shock if it comes into contact with live wiring. This can be
mitigated by always ensuring the power is turned off before work begins
and double-checking with a voltage tester.
Work gloves should also be worn as the steel tape can potentially
cause cuts and scrapes, and safety goggles are recommended as the tape
could recoil unexpectedly when pulling or pushing. Keep fingers and
other body parts clear of the enclosed reel to prevent possible pinch
points.
Metallic fish tapes, due to their electrically conductive nature, are
not to be used in live circuits. On the other hand, non-metallic fish
tapes, while safer to use near energized circuits, can snap or break if
they are forced around a sharp bend, leading to potential injury.
Furthermore, care should be taken not to extend the fish tape too far
without securing the previously laid part of the tape, as the tension
could cause it to whip back and cause injury. Lastly, as with all tools,
ensuring your fish tape is in good working condition before use is
crucial for maintaining safety. Regularly check for signs of wear and
tear and replace it as necessary.
By taking these safety measures into account, one can use a Fish Tape
effectively while mitigating most potential risks.
