Implementation & Installation
The straight ABS-Lock® DH04 model is implemented, for example, on slate roofs with paneling throughout. The device is installed by screwing two special screws through the paneling directly into the rafters. The cranked model is bent to allow installation on all common tiled roofs. This device is installed in the same way by screwing two special screws through the counter-battening into the rafters.
[Installation cross-section from left to right: 1. Through the paneling/OSB into the rafter, 2. Through the counter lathing and rafter insulation into the rafter, 3. Through the counter lathing into the rafter]
