Product Description

Rubber panel grommet 2561 is a pass-through component used to line openings in aircraft panels and bulkheads. Its primary function is to protect wires, cables, or tubing passing through a cutout by separating them from the sharp edges of the panel. The grommet helps maintain clearance and support for routed conductors in avionics bays, instrument panels, and other interior structures where harnesses or lines pass through sheet metal or composite walls.

0 1. Overview

The 2561 grommet is manufactured from elastomeric rubber and fits into a pre-cut hole to form a cushioned barrier between the panel edge and the routed item. The flexible construction allows slight deformation for installation while maintaining a snug fit around the opening. The part number is molded into the body for identification. Dimensional characteristics such as groove diameter and panel thickness range are defined so the grommet nests securely in the bulkhead or panel. The circular geometry centers the protected bundle in the opening and distributes contact stresses around the entire circumference. The component is supplied as a single-piece ring that is inserted into the cutout before or during harness installation.
