The Master AL Lock full-body harness is characterized by a revolutionary waist adjustment system that allows for covering a wide range of sizes. Another very interesting and useful feature for the user is the positioning loops, where the position of the loops (EN 358) can be adjusted exactly according to the user's needs.

The harness is very comfortable not only due to the excellent waist system but also thanks to the reinforced leg straps. A wide versatility is also provided by the variable slot system (combined with a webbing) on the back padding. The shoulder padding includes slots for storing small items (e.g., a knife, etc.).

Reflective elements, 6 classic material loops, and a haul loop are a given.
Adjustment is done using aluminum quick-release buckles. The loose ends of the straps can be secured using the SB system. The attachment points are made of aluminum, except for the rear fall arrest point, which is rarely used. This point is therefore also stored in a protective pocket and is only pulled out when necessary. In order to reduce weight, it is made of textile.

In front of the fall arrest point is an auxiliary strap with a small buckle to secure a chest blocker.

A reinforced elastic strap at the back of the seat ensures the optimal position of the leg straps relative to the waist in all possible worker positions, and it can also be adjusted using buckles.

The shoulder straps can be fully removed, and the harness can be used as only a seat harness.

The chest and seat harness are connected at the back with a metal ring.
