Adjustable wall mount for shaft ladders made of stainless steel. Note: For ladders with 4 - 9 rungs, 2 sets (4 pieces) of wall mounts are required; for ladders with 10 - 15 rungs, 3 sets (6 pieces) of wall mounts; and for ladders with 16 - 24 rungs, 5 sets (10 pieces) of wall mounts. 1 set consists of 2 pieces (1 x right, 1 x left). When attaching to the shaft, dowels and bolts may only be used instead of nuts and screws if their suitability at the location of the ladder's use has been demonstrated.
