Product Overview
The Chief WP21S is a short-throw projector wall mount with a fixed 24-inch extension, engineered to position and align a projector for wall-mounted short-throw applications. It is built for commercial AV spaces such as classrooms, training rooms, and conference rooms where the projector must sit close to the screen. The mount installs to wood studs, steel studs, and concrete and pairs with Chief RPA and Elite Series projector mounts (ordered separately).
Product Description

The WP21S provides accurate placement and alignment for short-throw projector installations. Its short-throw arm supports a projector close to the projection surface, and the projector mount slides along the arm for effectively infinite placement adjustment. Integrated micro-leveling and 1.75 inches of lateral shift let installers dial in a precise, square image. A 1.5-inch NPS collar provides compatibility with Chief RPA and Elite Series projector mounts, as well as other Chief accessories. The aesthetic covers and inlay-style cable management system conceal and protect cables for a clean finished look. The mount is designed for installation to concrete, block wall, brick, dual wood studs, or dual steel studs, and ships with hardware for wood stud and concrete walls. The WP21S includes the short-throw arm only; the projector mount must be ordered separately, and the arm is also offered in 40-inch and 56-inch lengths. The product is TAA compliant.
