Dry Wall Cable Trays

DRY WALL CABLE-TRAYS: Through drywall

Cable-trays can be treated the same as in concrete only if the hole is trimmed out correctly.

To achieve the required rating (same rating as the wall) through the hole, the hole must be framed around and then lined with the same material as the wall structure. e.g. timber 100mm x 50mm framing and 13mm Fyreline Gib. If the wall has two layers of Gib the hole must also.
