Klein Tools D504-10B – Frequently Asked Questions
1) What is the biggest pipe or fitting the Klein D504-10B Klaw pump pliers will grip?
Jaw capacity on the 10-inch Quick-Adjust Klaw pump pliers is 2.125 inches (5.4 cm), so they close down on anything up to roughly a 2-inch nominal fitting, conduit coupling, or nut. Above that you need a larger pump plier or a pipe wrench.
2) Are the yellow handles on these Klein pump pliers insulated for live electrical work?
No. The handles are plastic-dipped in yellow for grip comfort and tool identification, not VDE insulated. For energized work you need a tool rated and marked 1000V insulated; these are not that tool.
3) How do you adjust the Klein Quick-Adjust Klaw pump pliers one-handed?
A push button releases the ratchet so the lower jaw slides to any position, then locks when you let go. That means you set the jaw on the work with one hand while the other hand stays on the pipe or the box, instead of pinching the tongue-and-groove channels open the traditional way.
4) Will the jaw teeth chew up chrome trap arms and finished fittings?
The gripping teeth on the Klaw pump pliers are specially hardened for a positive bite and reduced wear, so they will mark soft chrome or plated brass. On finished trim, wrap the fitting with a rag or tape, or use a smooth-jaw tool. On conduit, steel nuts, and black pipe, the hardened teeth and multiple jaw contact points are exactly what you want for torque transfer.
5) How heavy are the Klein D504-10B pliers for all-day pouch carry?
They run 12.6 oz (358 g), light enough to ride in a pouch or on the belt through a full day of rough-in without loading down one side.
