Stage 4 – A) Identify the two types of cover clipping systems. B) The fitting of the covers
Type 1
:
Lockstrip
Lockstrip is used on the end hoops, and also a 200mm piece is used at the apex of internal hoops where the roof vent ends.
Lockstrip is a green coloured continuous strip “insert” and a small grey coloured “L” shaped locking “clip”.
IMPORTANT The insert and the clip parts must be positioned in the direction shown below (otherwise the cover will not be held)
The pre-cut 200mm length pieces of Lockstrip insert are only used on the front face of the curved part of each end hoop
The rest of the Lockstrip insert is supplied in full 1.5 lengths (trim these to length to suit). Also watch the video on the Redpath web
