Patent attributes
A locking retainer can be used with a slidable support that includes a two support member with respective sets of locking apertures, with the two support members slidably engaging each other to define a support profile. A strap can at least partly bound an internal area and can support a locking pin that extends into the internal area. The strap can have a locking configuration in which, with the slidable support disposed within the internal area, the locking pin extends into two of the locking apertures to lock the slidable support at a fixed length. A locking retainer can be installed by disposing the slidable support within the internal area, aligning two locking apertures of the slidable support, and applying lateral pressure to a side arm of the locking retainer to seat a locking pin in the aligned locking apertures.
