摘要 |
An adjustable universal safety scaffold and walkboard ladder holder that absolutely prevents scaffold collapse or dis-attachment from a construction project and absolutely prevents a ladder placed against a walkboard from slipping sideways. Vertical supports can attach attach top and bottom to the building or work under construction. Hold brackets that can be raised or lowered slide up and down the vertical supports. A walkway sits on the hold brackets and is positively held in place by pins. A ladder can be optionally leaned against the walkboard and secured by additional stay bolts into the walkboard to prevent horizontal slipping.
