CA 2127723
A gripping device is provided for use with vertical or near vertical timbers on building sites, especially with 2" x 4", 2" x 6", or 2" x 8" planks, and which allows such timbers to be used with a series of the devices forming steps of a temporary ladder. The timber may be leaning against a surface, or may be part of a scaffold or studs of a house. The device may be formed of a single piece of rod, or as a casting. 1t has a closed loop part suitable for use as a step, and also has a retaining part, the retaining part and loop having parallel portions defining an open sided recess for receiving the timber. At least one of the parallel portions has a set of teeth facing the other parallel portion, such that the device can be slid sideways on to a timber and can be pivoted down to cause the teeth to engage the timber and prevent further movement of the device.
