JGI Interlock™ Concealment System

The Interlock™ Concealment System is similar to the Soffi-Steel® System.  It is strong and durable, Made in the USA, and produced from A60/G90 galvanized steel with a few modifications for the purposes of greater economy.  The Interlock™ Concealment System is an economical alternative to typical drywall soffits and carries the FM Approval.

The "Snap-Lock" Connection, Interlock Concealment System. Pipes & Ceiling



Utilizing the Snap-Lock connection, The Interlock™ Concealment System is snapped securely into chromium plated spring steel shield clips. The unique "reverse curvature" between the clips and the cover keeps the pipe cover virtually irremovable once installed. Providing a secure, streamlined pipe cover for your facility's exposed pipes and mechanicals is a simple achievement. 


The custom-fabricated Interlock™ Concealment System is available in a variety of shapes and sizes to fit your individual requirements for pipe enclosures.  Our soffits are offered in two standard shapes to satisfy your individual project needs.  The L-Shield is primarily used for installations at the wall/ceiling or wall/floor line, and the U-Shield is best for ceiling soffit, and metal soffit, or vertical drop installations.  Both configurations can be manufactured at dimensions ranging between 2-3/4" - 60" and up to 10' lengths.
