Klein Tools SRS56037 Magnetic Wire Pulling System

You drop or feed the magnetic leader-pull into the cavity and steer it from outside the wall with the magnet, then connect your wire to the swivel leader eyelet and pull it back through. The leader-pull is non-marring nylon on 20 feet (6.1 m) of heavy-duty nylon rope, so it works through wall, floor and ceiling voids and other enclosed spaces where you cannot get a fish tape to turn.

Both. The swivel leader eyelet is made to connect to most wires and to mesh wire pulling grips, so you can tie off a single conductor directly or clip a grip onto a bundle of cable.

No. Never use the SRS56037 on or near live electrical circuits. De-energize the circuit first, and wear approved eye protection while pulling. It also generates a strong magnetic field, so keep it away from anything magnetically sensitive you are carrying.

The Klein SRS56037 carries 20 feet (6.1 m) of rope, which covers a standard single-story wall drop, a floor void, or a ceiling run with slack to spare. A full two-story chase from attic to basement will outrun it, so for those pulls plan on a longer fish system or staging the pull floor by floor.

The leader-pull body is non-marring nylon, so it is meant to slide against finished surfaces inside and around the cavity without scoring them. That is the point of the design on remodel and occupied-unit work where you are fishing behind existing finishes.

The leader-pull is shaped to navigate many obstructions inside a cavity, which is where it beats a flat fish tape that hangs up on framing and batt insulation. It will not drill through solid fire blocking, though, so a fully blocked bay still needs a hole bored before you can fish it.

Different tool. It is a magnetic wire pulling system: a rope-and-leader kit you steer with a magnet from the outside face of the wall, rather than a steel tape you push blind from one opening. Reach for a conduit fish tape when you are running through pipe; reach for this when you are working open voids, blind bays, or spots where you only have access on one side.

It ships on a spool inside a storage tube, so the rope winds up rather than knotting loose in a bag and the magnet stays protected between jobs. The whole kit weighs 6.4 oz (181 g), so it is no burden to keep in the van permanently.

Order Klein Tools SRS56037. That is the single model for this magnetic wire pulling system, so there are no length or finish variants to choose between.
