PVC-U is flame retardant and self-extinguishing. It provides a 100% recyclable material with good sustainability.

PVC-U expands and contracts at a uniform rate of approx 5.25mm in a 3 metre length for a temperature change of 25°C. Therefore, a 3mm gap between each length of trunking base is recommended.
Fittings allow for thermal expansion of the covers.

Mini trunking
Secure trunking base at least every 375mm by drilling 6mm holes.
Fasten using roundhead screws.
Self-fixing mini trunking
Remove protective film exposing 100-150mm of adhesive foam.
Line up accurately and press firmly into position. Repeat until base is installed. For long term performance we recommend additional securing with screws and washers.
Note: the bond created by the tape can be very strong. Maximum adhesion occurs after 24 hours. Ensure surface is dust-free, dry, clean and flat. Uneven surface contact will reduce bonding performance. Installation in cold conditions below +5°C may affect adhesion.
Mini and self fixing mini trunking
• Avoid over-tightening to permit thermal movement.
• The use of plastic caps over screw heads is recommended to protect installed cables.
• To cut the trunking, use a fine-toothed panel or power jig-saw.
• External profile fittings overlap joints by up to 10mm to cover cutting inaccuracies.
• A variable angle jig-saw or chop saw is recommended for cutting 45° mitres.
• End caps are secured using adhesive solvent BXSC.

• All fittings incorporate clip-on design.
• 3mm gap between trunking base and bend or flat angle is recommended.
• For internal bends and flat angles, bases should be mitred 45˚.
• For external bends, bases should be cut square to the corner.
• For tees, bases should be cut square and butt up to each other.
• External clip on fittings overlap trunking base by up to 10mm to cover cutting inaccuracies.
• Secure end caps using solvent adhesive BXSC.

Covers are designed to limit unauthorised removal and to remain in position during normal conditions irrespective of impact and minor undulations of the mounting surface.

Covers are clipped into place from front.

To remove a cover, first detach a coupler or internal/external bend to gain access. The cover can then be gently eased off the base.
