Whether you work in the roofing or flooring industry or are just looking for an aid working in the garden or on home improvement projects, this pack contains a pair of knee pads and a pair of patented attachable non-marring caps that will help protect your most important asset; you! The knee pads are designed to be hard-wearing; the heavy duty 1680D polyester fabric has been tested up to 7,000 abrasion cycles so you can feel confident knowing they can hold up against a wide variety of surfaces ranging from construction site concrete and subflooring to at home hardwood and tile. The compression gel core is further padded with EVA foam to help to both absorb hard impacts and disperse bodyweight. The inner layer's lightweight, water-resistant compression gel and EVA foam construction pads and conforms to your knees for a comfortable fit and the single neoprene strap design makes them a breeze to put on and take off. When working on delicate surfaces, the included non-marring caps can be attached using the built-in twist-to-lock anchors to add an additional layer of protection to your knee pads. These included caps are made of flexible TPE copolymer to shield delicate surfaces like hardwood and tile flooring from damage. When a task calls for working on your knees, let PROLOCK knee pads take the strain so you don't have to. Set includes 1 pair of PLK04 (93181) knee pads and 1 pair PLK06 (93179) non-marring cap attachments.
