Unifold Clip Joint System
Unifold Clip Joint System is a patented system used to allow the installation of Unifold in difficult access
situations where the gutter is narrow, small or where sheet overhang is excessive and prevents access to
the extremes of the Unifold or where drill and rivet penetrations are un-desirable. Patent Number 2376481.

Expansion and Contraction joint
Lining systems need expansion and contraction
joints in certain circumstances to ensure that
outlet liners remain in position and fabrications are not stressed by
thermal or structural movement and to enable the system to
move in complete conjunction with the existing gutter
beneath. It is an integral part of the system and is
manufactured within an individual length of Unifold.
It is used to coincide with building expansion
