A roller extension slide including first and second track beams, a center beam of box section with wheels projecting through clearance openings of lateral webs engaging track surfaces of the track beams; guide flanges of the center beam engaging guide slots of the track beams for maintaining the track beams closely spaced; and the travel slot formed in each track beam. Center wheel axle extensions engage opposite ends of travel slots in the track beams for limiting the travel between retracted and extended positions of the track beams, with track beam wheel engagement spacing being at least 80% of the track length the first position and at least 40% in the second position, an extension distance being at least 80% percent of the track length, the first position being with the apparatus substantially contained within the track length. Also disclosed is a table incorporating a pair of the extension slides.
