Spring-Loaded Plunger Assemblies Move Sliding Components to New Positions Without Tools

PEM® Type PTL2™ spring-loaded plunger assemblies from PennEngineering® ideally serve as reliable positioning pins to quickly move racks, slides, access panels, consoles and similar equipment to new positions without requiring tools.

A unique lockout feature in the standard product line keeps the fastener's spring-loaded plunger fully retracted until the plunger pin drops into final position. A simple quarter-turn of the fastener activates the retracted locking and unlocking functions.

Type PTL2 spring-loaded plunger assemblies install permanently in aluminum or steel sheets as thin as .060" / 1.53mm with hardness of HRB 80 or less. Their engineering allows the reverse side of the sheet to remain flush when the plunger is retracted.

Easy installation begins with a properly sized mounting hole in the host metal sheet. The fastener is placed into a recessed anvil and then the work piece (punch side) is placed over the fastener's shank. With punch and anvil surfaces parallel, squeezing force is applied until the shoulder of the fastener's retainer comes into contact with the sheet material, which completes the installation process.

For applications where the lockout feature is unnecessary, companion Type PSL2™ spring-loaded plunger assemblies can be supplied on special order.
