Angle Frames

Angle frames are an economical solution to many expansion joint applications. They can be made from standard structural angle or fabrictated from plate. Depending on different application, they may be used with or without baffle liners.

Low Profile Angle Frames

Angle frames are an economical choice and are fabricated from standard Structural profiles angle frames, and also favored since they can be shipped fully assembled which reduces field labor costs. They may be supplied with or without baffles.

Z-Frames

Z-frames are one of the most popular, robust, and easy to install frame styles. Z-Frames include dual-overlapping baffle liners which are an integral part of the frame. Z-frames are ideally suited for both high temperature and heavy particulate flow medias. Z-Frames can be welded to the duct mounting flanges or supplied with seal welded nuts for “ bolt-in “ installation.

J-Frames

J-frames include integral outboard flanges which allow them to slide easily in between two mounting flanges without any need to pre-compress the joint or jack open the breech. Additionally, a J-Frame may include either double overlapping or single sided baffle liners. They can be integral to the frame or field welded at the time of installation.

Channel-Frames

Channel frames are fabricated with standard C/MC Structural Channel and may include either integral ( factory ) installed or loose ( field welded ) baffle liners. Channel frames may provides additional support and structural rigidity to the duct opening.
