Duralock Film Clipping Systems

Duralock2 film clipping system:

Duralock2 is Redpath’s continuous bead fastening system for film and fabric and in recent years has replaced the ageing Lockstrip clipping system.
Duralock2 is a more affordable and simple to use system and is specifically designed to reliably retain a variety of polythene film and fabric claddings. Duralock2  has a  “self-locking” design promotes the secure grip the cladding in windy conditions.
It is simple and easy to assemble with the base aluminium profile being screwed to the framework.  The white  “channel” part is then insertedinto the jaw of the aluminium followed by the “locking bead”.  Duralock2 is easy on the cladding and is less prone to damaging the cladding during assembly if inexperienced.

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 is used to secure a wide range of thickness claddings from 100 – 500 microns.

To hold claddings up to 350 MICRONS choose the 1.5m length  “LONGLEG”  bead type
For materials of 351 micron and over such as twinskin polythene or light/medium shadecloth using the 2.25m length  “SHORTLEG” bead.

Duralock is available in both single groove and twin groove base aluminium designs, and also a rail design (see below),  use the Twingroove base where joining of sheets on rafters or where two sheets come together such as on the end of a building.
Duralock is supplied in 4.5 metre lengths complete with all parts (base, channel and bead insert) – but can also purchased the individual parts (see below)
