Abstract
A safety clamp slidably mounted on a vertical safety rail in proximity to a ladder is attached to a workman's belt by a pivotal actuating arm which shifts a wedge plate into clamping engagement with a safety carrier immediately under free fall conditions encountered if the workman falls from the ladder. The rail is spaced from the ladder mounting brackets by circular sleeves.
