Mobile Stand-Off devices are essential parts of a hook ladder. They maintain the distance of the ladder from a wall assuring safe position of feet on the rungs.
These devices can be placed to any part of a ladder depending on the wall profile. They can be also used on the Emergency Stretcher to prevent contact of an evacuated patient with the ground.
Simple design consists of an aluminum clamp secured by a bolt with a wing nut and replaceable stand-off extenders with anti-slip rubber foot. Extenders are available at 2 different lengths. Special wing nut allows easy manipulation even with gloves and it is secured against unintentional release.
