Klein Tools 5416T Tool Bag, Bull-Pin and Bolt Bag, Tunnel Loop, Canvas, 5 x 10 x 9-Inch

Yes. The 5416T uses a tunnel loop belt connection sized for belts up to 3 inches (7.6 cm) wide, so any standard ironworker or electrician's belt in that range slides straight through. Because it's a tunnel loop and not a clip, you have to unbuckle the belt and thread it on rather than snapping it in place.

No separate holder needed. The 5416T has a bull-pin loop on each side of the bag, so you can carry a pin on both the left and right while the main body stays free for bolts and nuts. Two loops also means a right- or left-handed worker gets the same reach.

The bag measures 5 x 10 x 9 inches and weighs 0.9 lbs empty, with 3 pockets inside. That footprint is sized for a working handful of bolts, nuts and spud wrenches on the belt, not for a full tool kit. If you need to carry a larger bolt load or longer tools, step up to a bigger bolt bag.

The 5416T is built from No. 4 canvas with a double bottom, and the seams are both stitched and riveted. The double bottom is the part that matters when you're dropping threaded rod and bolts in all day, since that's where a single-layer bag wears through first. Canvas won't crack in cold the way a hardened plastic pouch can, but it will absorb water, so it isn't the pick if the bag lives outdoors in the wet.

A tunnel loop like the one on the 5416T captures the belt through the back of the bag, so it cannot pop off under load, which is why it's the usual choice for bull pins and heavy bolt loads up on steel. The trade-off is swapping: you unbuckle to move it. If your crew shares bags between belts or drops them off mid-shift, a clip-on or snap-on style is quicker. For a bag that stays on one worker's belt all day, the tunnel loop is the stronger connection.

Order Klein Tools 5416T. That's the full manufacturer part number for the natural canvas tunnel-loop bull-pin and bolt bag, and it's a single configuration, so there are no size or color options to specify.
