JUNCTION BOX FIRE PROOF

The mounting hole diameter is 86 mm, drilled with a hole saw, and the hole must not be finished in any way. The box must be centered in the hole. The box has two screw studs with a center-to-center distance of 70 mm (for M4 screws), compatible with all standard ceiling covers (including those compliant with the DCL standard). The green spacer ring supplied with the box is used for single-layer ceilings (12.5 mm) and must be removed for double-layer ceilings (2 x 12.5 mm).

The box has one open knockout for a 16/20 mm pipe, totaling eight knockouts. The box is supplied with a cover AU67.70.
