Vertical Alignment
Connections - The Wellclaws
Horizontal and diagonal bracing are fundamental in the structure of scaffolding, with claws
locking them onto frames. It ensures rigidity and squareness of the erected structure.
Unlike conventional claws, Wellclaws are specially designed for easy installation and difficult
detaching. Efficiency of assembling should, under no circumstance, be achieved in the
expense of safety. While the one-hand snapping onto frames facilitates the quick and
self-locking assembly, the pulling motion required to unfasten the latches ensures that two
hands area required, eliminating the possibility accidental loosening or detaching.
The hook latches of horizontal and diagonal bracing are in green and in red respectively for
identication purpose.
Using a spirit level to set the adjustable legs and check the frames are vertical and level.
