REED Tripod Pipe Vises are among the strongest pipe vises available. They are manufactured with heavy gauge steel, overlapping hinges, and the best adjustable tray clamp, not a set screw, to keep the lower tray assembly and entire portable workbench tight, even after many hours of use. The heavy-duty design permits use with pipe up to 6” diameter. Tripods fold into a compact shape, have a padded handle grip at the balance point, and boast the lightest weight for the easiest portability of all well-known tripod pipe vises.
