Pipe Covers: JGI Interlock™ Concealment System

Soffit Available in ANY Size - Request a Quote!


The Interlock Concealment System is similar to the Soffi-Steel® System. It is strong and durable, made in the USA, and produced from USA 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.


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 in any combination of dimensions ranging between 3" - 60" and up to 10' lengths.


Available in #4 Stainless Steel, Paint Grip (for field paint), and Sherwin Williams Powder Coated finishes. The security grade Soffi-Steel® System retains its security and aesthetics, even in the most abusive circumstances.


The Interlock Concealment System is a custom-fabricated, utility concealment solution allotting you an exact soffit systems shield to satisfy your individual project's needs. Initially designed for high security purposes, the Interlock Concealment System's clean design and durability make it perfect for commercial and residential use, especially where the aesthetics of the system shield are just as important as its function. Our system is an excellent alternative to the time consuming and dusty drywall systems
