Abstract: A ladder stabilizer where respective ladder rails 12 and 13 pass through rail clamp sections 14 and 15 so that the feet 16 and 17 of the ladder engage the ground. The stabilizer has feet 18 and 19 which also engage the ground. These are at the end of a rail providing respective outriggers 20 and 21 so that the stabilizing forces and moments are across the bottom of the ladder. Clamps make the whole stabilizer and ladder rigid. Rails 12 and 13 are clamped in the clamp sections 14 and 15 which are in turn clamped along the outriggers, the feet are also clamped in height adjustable position. Hand operable screw clamps 22, 23, 24, 25, 26 and 27 permit adjustment so that the legs and rails and clamp sections may be positioned to best stabilize the ladder 11.
