Angle Iron Beam Clamps for Threaded Rods


	Shown With One Pair of Angles	Shown with Two Pairs of Angles

A secure way to hang threaded rods from a pair of angles, such as those used in ceiling joists, without the need to drill or weld. These clamps are commonly used to suspend HVAC, conveyor, and other overhead systems. They may also be used to connect two pairs of angles at 90°. Clamps are zinc-plated steel for good corrosion resistance. Each clamp includes a bracket and square washer. Secure with a hex nut (sold separately).

Capacity is the maximum load for two clamps holding a pair of angles across parallel joists. The values listed are for the maximum distance between joists, which is 6 ft. For shorter distances, capacities are higher.

Threaded Rod Mounts

Style A

Fasten these brackets to ceilings, walls, beams, and joists to hang threaded rod.

Note: Capacity is for the mount only. Mounting surface and fastening hardware will affect the ultimate capacity.

Style A—Style A mounts install flush against the ceiling. They are also known as nut plates. To use, screw threaded rod directly into the threaded hole.

Zinc-Plated Iron—Zinc-plated iron mounts have good corrosion resistance.

Snug-Fit Clamp Pipe Hangers

Place pipe between the hanger halves and adjust the side bolts for a tighter fit than other pipe hangers. When closed, the split ring forms a complete circle around the pipe for 360° support with no gaps. Mount by twisting a threaded rod through the threaded hole.

Zinc-Plated Iron—Mildly corrosion resistant, so these hangers are ideal for dry or slightly humid environments.

Epoxy-Coated Iron—Resist corrosion better than zinc-plated iron.

Roller Loop Pipe Hangers

Compensate for linear movement as pipes expand and contract. The roller turns to accommodate motion as pipes carry fluids and gases at fluctuating temperatures or pressures. Attach to the ceiling with a threaded rod and nut (sold separately) or other fastener.
