Ceramic tile fitters have to spend long periods of time kneeling on the floor, constantly bearing loads and repetitive movements. Movements which can take their toll in the long term. The ergonomic and extremely comfortable RUBI GEL DUPLEX knee pads combine the use of hard materials to protect against knocks and uneven floors and soft materials inside, which adapt to the body of each user. In addition to protecting the user's knees owing to the silicone gel inside, their studied ergonomics make them extremely stable, avoiding ligaments and tendons taking excessive strain. The GEL DUPLEX professional knee pads can be used by a wide range of professionals in the construction sector, owing to their two-in-one design. This feature of RUBI GEL DUPLEX knee pads incorporates a highly stable and resistant outer rubber protection that can be removed according to the user’s preferences and needs. This leaves, if the job requires so, a less cumbersome main body, enabling the knee to slide easily on smooth surfaces. GEL DUPLEX knee pads feature a double fastener, with a quick-fastening system on the upper band and a lower easy-to-adjust mechanical fastener. These features ensure a firm and comfortable fit and moulding around the leg to the body of each user. At RUBI we have always been concerned about the health of professionals. The concept of ergonomics is always present within the design of our tools, as we believe that safety and minimizing the risk of injury at work are essential for health and proper performance. This is why RUBI GEL DUPLEX knee pads are manufactured in compliance with the EN 14404 standard and give the user level 1 protection level.
