Film Clipping Systems

Duralock2 film clipping system:

Duralock2 is Redpath’s continuous bead fastening system for film and fabric. It is specifically designed to reliably retain all widths of claddings up to 14.4m wide. Duralock2  “self-locking” design means that “the harder the wind blows the tighter the Duralock2 will grip the cladding”.  Duralock2 is simple and easy to assemble with the base aluminium profile being screwed to the framework and then the “channel” UPVC strip part of the Duralock being pushed into the jaw of the aluminium followed by the “locking bead” UPVC part.  Duralock2 is very easy on the cladding and is unlikely to damage the cladding during assembly.

Duralock2 incorporates a “shading cap” along the front edge of the channel insert to help protect the cladding from the heat of the sun.  Duralock2 may be used to secure claddings in thickness of up to 400 microns (white bead), and 401 microns and above (green coloured bead).  It is ideal for singleskin or twinskin applications. Duralock is available in both single groove and twin groove designs. Other profiles and individual parts are also available – please use the enquiry form below for these.

Duralock is supplied in 4.5 metre lengths – and comes complete with the base, and both inserts. (No screws supplied)

Lockstrip film clipping system:

The original Redpath patented design clipping system and used for more than 30 years throughout Australasia.  Lockstrip is also a “self-locking” design that tightens as the wind load on the cladding increases.  Two inserts are available for the Lockstrip system. One to suit claddings of up to 350 micron (longleg), and one to handle thicker claddings (shortleg) to both fit our aluminium base already attached to the buildings framework.

Other profiles and individual parts are also available – please use the enquiry form below for these.

Wire and cable clipping system:

Redpath “Omega” Clip is utilised for the semi-permanent retaining of films and fabrics onto wires or cables. This system is designed for moderate cladding widths only, in sheltered locations. Omega clip is often used as a temporary retainer of cloche films or for side wall netting and film at greenhouse ground level.
