Two Round Ends
FEATURES: Small, lightweight, economical locking hub that is still
extremely durable. Made of black thermoplastic, these Adjustable Locking
Hubs are rotary bearings that provide positive locking at any 15°
increment. Once locked, the hub becomes an absolutely rigid joint, able
to withstand 7 ft-lbs of torque (5:1 safety factor). Applications
include adjustable fixtures, rotating fixtures, trunnion mounting,
adjustable handles, foldable handles, adjustable part trays, adjustable
shelves, adjustable racks, adjustable and/or fold-away work surfaces,
positive positioning of lighting or nozzles, and collapsible structures.
Patent numbers 5,586,363 and 5,689,999. Other patents pending.
OFFSET MODEL: Available only as an offset model. Hub extensions are
offset to allow full 360° rotation. Offset hubs should usually be used
in pairs, to avoid off-center loading on a single hub and ensure full
strength. Make sure that rotating loads are balanced.
MOUNTING: The version shown here has round hub extensions to fit 5/8" ID
pipe or tubing (snap-on fit).
SAFETY PRECAUTIONS: Avoid any possible pinch points, especially with
heavy loads. Do not release the hub unless adequate support for the load
is in place. Do not let loads swing freely. When using offset hubs that
can rotate 360°, always ensure that loads are balanced in the rotational
