DobyGrip Wire Suspension System

The DobyGrip wire suspension system locker has a durable, strong, yet ergonomic zinc cast body with patented gripping wheel design, and inbuilt release mechanism. These are just some of the features that combine to produce fast, efficient installations when used in conjunction with our galvanised steel wire rope. Available in kit form, with pre-cut, individually banded wires and an expanding range of end fixings. Individual DobyGrip wire suspension lockers are available with 100 - 150m reels of wire across 1 - 6mm diameters, reel length is dependent on wire gauge.

The body of the DobyGrip locker is cast in Zamac 5 Zinc for durability and strength under pressure. Internal guide springs are manufactured from a quality 304 Stainless Steel giving just enough pressure to push the gripping wheels away when needed, whilst the wire is held securely in place by the wheels and friction gearing. The gripping wheels themselves on the DobyGrip wire suspension locker are produced in high-quality solid steel as a single piece, again for strength. With very few components and the ability to accurately adjust without the need for extra tools, the DobyGrip wire suspension system has a proven track record of safety and product confidence to be proud of. Our "Belt & Braces" design approach to the lockers has resulted in a first-class, quality product of reliability and functionality.
