The tapered, rubberised ‘limb’ of the LadderLimb fits snugly into the ladder, holding whatever is attached to it securely in place. And, when you wish to work at another height, the LadderLimb™ can be easily and effortlessly withdrawn and placed into another rung.

Simply attach the item, for example, your paint can, to the LadderLimb™ clip and take it up the ladder and inserting it into the hollow rung at your chosen height The tasks performed consisted of climbing and descending the extension ladder and the fixed ladder. Participants were instructed to climb either the fixed ladder or the extension ladder based on an alternating cycle. Cycle A starts with ascending the portable extension ladder. Cycle B starts with ascending the fixed ladder. Cycle A is used to explain the procedure. The participant would attach their harness D-ring to the retractable lifeline hanging from the ceiling-mounted anchor shown in Figure 2a. They would then climb the extension ladder and step onto the mezzanine. They would then disconnect the retractable lifeline, walk to the mezzanine hatch, hook their dorsal D-ring to the davit shown in Figure 2b, and proceed to descend the fixed ladder. After completing their descent and briefly pausing, they would ascend the fixed ladder. After stepping out of the hatch onto the mezzanine, they would disconnect from the davit, walk to the extension ladder, hook up to the ceiling anchor cable, descend, unhook, and doff their harness.The versatile LadderLimb™ makes so many tasks so much easier, whether it’s cleaning out gutters, washing the caravan, pointing or repainting the house, cleaning your windows or pruning trees and bushes… your customers will wonder how they ever managed without one!

Hammer and Schmalz studied effects of ladder inclination on limb-movement pattern using 28 subjects [ 18]. They found pattern preferences depended on whether ascending or descending as well as the ladder angle. For example, for ascending they found: No matter whether you are a DIY hero or a trades champion, LadderLimb will help you be safe whilst working at height.

So if you’re using a ladder for those weekend jobs or everyday at work, our ingenious ladder safety device will leave you with both hands free. Each of the cited studies contributes to the present state of knowledge, yet important questions have not been answered. The first concerns the taxonomy of limb-movement patterns depicted in Figure 1. Does the taxonomy include all patterns that might be used for three points of control climbing? Does the taxonomy include any patterns that are not practical or simply not used? All the cited studies [ 10, 11, 12, 13, 14, 15, 16, 17, 18] were based on defining the same four limb-movement patterns. In terms of the six possible patterns depicted in Figure 1, only Patterns 3 and 5 have been studied. Pliner and Beschorner mention they excluded from analyses subjects who had two successive hand movements per foot movement [ 11]. That would exclude Patterns 1, 2, 4, and 6 in Figure 1. The LadderLimb™ is a simple, easy-to-use device which fits effortlessly into any of the hollowed rungs at either the left or right hand side of a ladder and at any height. It’s a handy tool and safety device for gutter cleaners, decorators, roofers, window installers, insulation installers, window cleaners, electricians, plumbers (yes they use ladders too), builders, joiners, gardeners, maintenance teams, facilities management, lighting installers, tv and satellite installers, rough-casters, telecommunications engineers, cctv installers and many, many more.
