Linerloks and Plugloks

Linerloks are a low profile, non-destructive (no holes through the substrate) method for fastening a polymer liner to the substrate.  They are placed inside the countersunk holes on the panel. If you are installing a Smooth Move lining kit these hole profiles will already be in the proper locations on the sheet. If you are drilling your own liner, two-stage Linkerlok tools are available.  Linerloks or weld washers are typically used when there is no access to the backside of the unit being lined and/or you are installing a thin liner and need a low profile fastener.  A weld pool is created in the inside hole of the linerlok bonding the fastener to the surface of the substrate.  After the Linerlok is installed the top will be1/4" off the surface of the steel.
