PEM Type PTL2 spring-loaded plunger assemblies allow users to quickly and easily move racks, slides, access panels, and similar equipment to new positions without requiring tools. If necessary, a unique lockout feature keeps the fastener’s spring-loaded plunger retracted until the plunger pin drops into final position. A simple quarter-turn of the fastener enables the retracted locking and unlocking actions.
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 or HB 150 or less. Their engineering allows the reverse side of the sheet to remain flush when the plunger is retracted.
These fasteners install reliably into properly sized mounting holes in a 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, installation is completed by applying squeezing force until the shoulder of the retainer comes into contact with the sheet material.As a variation of these fasteners, Type PSL2™ spring-loaded plunger assemblies are available on special order without the lockout feature.
