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.

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.

Ceiling Tiles

High density mineral fiber tiles have a thick coat of latex paint, making them durable enough to withstand bumps and scrapes. Melamine foam tiles are black on one side and white on the other.

Tiles with recessed edges are indented on all four edges so the installed tile face extends below the support framing.

Because of their scattered, non-directional pattern, fissured and fine fissured tiles can be installed in any direction. This reduces installation time and scrap material. Fine fissured tiles have a smoother appearance than regular fissured tiles because of their smaller crevices. Directional fissured tiles create a more uniform appearance than the fissured and fine fissured tiles.

Ceiling tiles that absorb 70% of sound are best for busy environments, since they reduce how far voices will carry in an open office. Ceiling tiles that absorb 80-85% of sound are best for noisy environments such as conference halls and performance spaces.
