T-Slotted Framing Pivots

Pivots provide smooth motion at the junction between two T-slotted rails.

Locking inline/perpendicular pivots have a handle that locks in place to position parts or hold doors and lids open. Align the tabs to install the pivot at the end of the rail. The two tabs parallel to the T-Slot must be removed prior to installing the pivot perpendicular to or inline with the rail.
