The DEWALT DXSTAH025 Adjustable Shop Stool Casters was designed and engineered to provide a heavy-duty stool for use in the busiest workshops and professional garages. The comfortable foam-padded textured vinyl seat sits atop a 360-degree swiveling pneumatic piston allowing free and easy rotation when seated. This all-steel frame construction stool can easily hold up to 300 lbs. without showing any signs of weakening or metal fatigue. The 4.25- inches of height adjustment can be set at any height from its lowest of 22.5-inches to a maximum of 26.75-inches so you can set it to what best suits you. A bolt-secured wire grid lower shelf provides extra storage for tools/supplies. Pre-assembled with 360-degree swivel casters leaves only the seat and pneumatic adjustment cylinder to be attached before the stool is ready for use. If desired, the casters can be removed and replaced with the included rugged, glass-filled nylon feet with levelling shims to protect floors.
