Prime-Line Plunger Bolt for Screening

This is a spring-loaded nylon plunger bolt with snap-on plastic caps that holds aluminum-framed screens in window channels. Typically used with 1/4 inch and 5/16 inch screen frames. The spring-loaded plunger drops into a 7/32 inch hole drilled into the screen frame. If you frame is not already predrilled for the plungers use the Prime-Line part P 7922 Step drill bit for best installation results.
