Large Anti-Slip Mat: The dimensions of the door handle anti-slip mat are 23 x 7.3 x 0.6 cm. You can distribute the weight while charging, and the soft, non-slip PVC also protects the frame from cracking and preventing damage from sudden drops. No screws, no drilling: installation and removal takes just minutes from the door frame. Simply turn the lever to press against the door frame. Be careful not to use pull-up bars with glass doors, hollow core doors, or other fragile door frames. STURDY SAFETY MECHANISM: The patented safety closure prevents the pull-up bar from rolling during use, keeping you safe. Don’t worry about damaging the door frame by over-tightening the pull-up bar. ADJUSTABLE UP BAR: Custom length, easily installs on most door frames between 70-90 cm. Fits standard doors, perfect for home, garage or office use. - Stand: 200kg Comfortable handles: Unlike other foam handles, these handles are made of highly elastic rubber and nylon, which are non-slip, non-toxic, odorless, and very comfortable.
