the r2003 takes up thermal and structural movement (the movement for each size is in the profile specifications below) while the cover stays seated on both sides of the joint.
the r-2003 has a continuous water barrier that laps into the roof waterproofing on both sides of the joint, without punctures, forming the primary watertight line. the cover plate and epdm inserts above it form the secondary line, so the roof stays dry as the joint moves.
this video demonstrates the assembly process, perfectly designed for easy installation for durability and reliability.
The R-2003 cover plate is aluminum, 2 mm thick (3 mm where scheduled), in mill finish as standard with clear anodizing optional. Sitting in recessed frames across joints of 50 to 250 mm, the 40 mm high cover gives roof joints a clean, continuous metal line.
