Abstract: A system including an insert including a body defining an inner cavity at a first end thereof. The insert includes an anchor having an opening formed therein, and the opening of the anchor is positioned in the inner cavity of the insert. The system further includes a spacer having a first end that is couplable to a second end of the insert to thereby adjust a height of the insert. The spacer is configured to be coupled to another spacer at a second end of the spacer.

Abstract: A system including a reinforcement positioner having a body with a longitudinally-extending spine and a plurality of legs coupled to the spine along a length thereof and at least partially extending away from the spine. The positioner further includes an opening or recess positioned in the body, and a clip configured to be received and retained in the opening or recess.

Abstract: A slab bolster including a longitudinally-extending spine and a plurality of legs coupled to the opposite sides of the spine and extending away from the spine. The slab bolster has a frangible portion along which the slab bolster is configured to be manually broken to allow the slab bolster to be manually separated into at least two parts.

Abstract: A rebar coupler having a casing with two opposite ends disposed along a central longitudinal axis. Each opposite end includes a frustum-shaped internal wall tapering along the axis from an inward to an outward position, as well as an assembly of a plurality of locking jaws, arrayed around the axis and engaging the internal wall, at least a portion of a spring, aligned with the axis and engaging the locking jaws, and a spacer, initially positioned within and engaging the locking jaws to separate the locking jaws and bias the assembly towards the inward position. The spacer is ejectable from the locking jaws through a center of the spring by insertion of a rebar end through the outward position and past the initial position of the spacer, whereupon the spring biases the locking jaws toward the outward position and into full engagement with the rebar end.

Abstract: A handheld multifunction power tool includes a driveshaft, a hub assembly, and a stem. The hub assembly includes an outer hub and an inner hub that is rotatably coupled with the inner hub and rotatable with respect to the outer hub. Rotation of the inner hub relative to the outer hub facilitates selection from among a rotary mode and a random orbital mode.
