Frequently Asked Questions
Can this bushing be installed without tools?
Yes. The flexible perimeter fingers compress as the bushing is pressed into a 1.25-inch hole and snap out behind the panel to lock it in place.
What is the inside diameter for cable clearance?
The inside clearance diameter is 0.937 inches (23.8 mm), accommodating wire bundles, tubing, or cables up to that diameter.
What panel cutout diameter is needed to install this bushing?
It installs into a standard 1.250-inch (31.75 mm) round hole in panels up to 0.125 inches (3.2 mm) thick. Order more and each piece costs less - the price-break table on this page spells it out.
Sheet metal holes have a habit of eating wire insulation if left unguarded. Snap this collar into the punchout, run your harness through, and keep the sparks where they belong.
