When constructing the masonry wall, the CTP MAD 2000 sleeves are embedded in the mortar of the bed joint or the CMU grout. The mortar then keys through manufactured openings to create a solid connection to the masonry. Two connecting rods are spaced with flexible plastic tubing to allow for telescoping movement. The flexible plastic tubing ensures expansion via properly spaced sleeves and the prevention of mortar build-up during construction. The CTP MAD 2000 sleeves can be embedded in masonry bed joints or fastened to existing construction. These sleeves do not require on-site fabrication or sash grooves. They can be added to existing walls if expansion joints are required.
