Vibration-Resistant Captive Panel Screws

An expanding rubber bushing damps vibration while holding panels together. To install, push the threaded end through a hole in the outer panel, slide on the bushing, and tighten the nut. Next, insert the assembly through the inner panel hole and flip the handle to fasten. They become a part of the panel when installed, so they won't fall out and get lost.

Brush-Style Furniture Grommets

Wire, cable, and cords pass through the grommet opening while the bristles fill in the gaps to control dust and debris. Use these grommets to eliminate cord clutter on desktops, countertops, benchtops, and other work surfaces. Push them into place.

Zinc alloy grommets are more durable than plastic grommets.

Wide-Airflow Bend-and-Stay Air Nozzles

The flat shape distributes air over a wider area than focused-airflow nozzles. These nozzles are attached to a flexible hose that bends and holds its shape until you reposition it. All conform to OSHA 29 CFR 1910.242 requirements for maximum air outlet pressure and OSHA 29 CFR 1910.95 requirements for noise.
