The DL 50 door loop with metal flexi-tube and housing for enhanced security is used to simplify and protect transmission of signals with a cable from  windows and doors to the frame.

It comes complete with 2 junction boxes in metal with opening and pry off protection and a stainless steel flexi-tube. The stainless steel flexi-tube is  available in 2 lengths – 400 mm and 600 mm.

The cable is protected against the sharp edges of the flexi-tube at each end with a plastic conduit that allows a maximum cable diameter of 4 mm.

The flexi-tube is secured with locking grooves in the base of the box for a safe connection. Each junction box has a 10-screw terminal with wire  protection, 2 of which are specified for the tamper switch.

If other lengths of the stainless steel flexi-tube are required the MC T2, MC T4 or MC T7 are suitable.
