Threaded Rod Mounts
Fasten these brackets to ceilings, walls, beams, and joists to hang threaded rod.
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.
Style B mounts have an offset bracket that attaches to the ceiling. To use, screw threaded rod directly into the bracket.
Style C and style D mounts have an offset bracket that attaches to the wall. To use, screw threaded rod directly into the bracket.
Style E and style F mounts install flush against the wall. To use, insert threaded rod into the mounting hole and secure with a nut (not included).
Zinc-plated iron mounts have good corrosion resistance. 304 stainless steel mounts have excellent corrosion resistance.
Note: Capacity is for the mount only. Mounting surface and fastening hardware will affect the ultimate capacity.

Threaded Rod Anchors
Install directly into a mounting surface to suspend threaded rod.
Anchors for steel have a sharp cutting point for mounting directly into steel. Use a drill along with the drive socket (sold separately) for installation.
Anchors for wood require a drill along with the drive socket (sold separately) for installation.
Anchors for concrete require a hole drilled by an ANSI 1/4" masonry bit. Use a rotary hammer or hammer drill along with the drive socket (sold separately) for installation.
Anchors with a 45° pivot angle have a swivel head, which makes them best for use in walls and ceilings that have an angled pitch.
Note: Capacity is for the anchor only. Mounting surface will affect the ultimate capacity.

Angle Iron Clamps for Threaded Rod
A secure way to hang threaded rod 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.

Suspension Beams for Threaded Rod
Mount these beams across parallel roof joists to hang threaded rod and route pipe, duct, and other overhead systems in areas where there’s no anchoring point. Beams are shaped to fit beneath corrugated roofing. They include a threaded rod anchor for supporting a single threaded rod. Add more threaded rod anchors to support additional threaded rod and customize your setup.
