Abstract
A blockout mold is mountable on an anchor bolt to enable a recess to be formed around the anchor bolt when concrete is poured, and is easily stripped from the recess after the concrete has set. The blockout mold has a body and a neck portion with an elongate bore therethrough to receive the shank of the anchor bolt. Pairs of vertically spaced slots in the neck portion enable a releasable clip to selectively secure the neck portion to the shank; while the body has a sleeve of compressible material to enable the blockout mold to be stripped from the recess.
