ABSTRACT:
Presented is a holder for retaining an anchor bolt in position for partial embedding in concrete poured into a form to which the holder and anchor bolt are secured. The holder is formed by a pair of side-by-side leg members connected integrally at one end so that any attempt to separate the legs imposes a resilient bias on the legs tending to return them to their side-by-side relationship. The legs are formed on adjacent sides with registering notches in which the anchor bolt may be engaged. A sheetmetal clip is mounted on one of the legs for axial displacement therealong, and includes a pair of opposed notches for registration with the registering notches formed in the legs to more securely grip the anchor bolt. Detent projections are formed on the sides of the clip cooperating with apertures in the leg on which the clip is mounted to releasably retain the clip in an axially adjusted position. A slidable collar embraces both legs and may be slid into binding engagement with the legs adjacent an anchor bolt supported by the holder.
