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. R470+ offers the same great features as REED's R450+, but R470+ provides a 60 percent larger top tray and a 45deg cranking handle. All REED tripod pipe vises offer double-sided, patented "bowtie jaws" for 15% extra value versus purchase of a second jaw set. Reverse the jaws for an extra face and save the cost of buying a replacement set as soon. Exclusive double-faced jaws on the R450P, R470P and R470PAL offer one neoprene side for plastic pipe/soft metals and the other regular jaw for metal pipe. Neoprene jaws provide protection against damaging plastic pipe and soft metal pipe. Jaws are easily rotated from plastic pipe to metal pipe position to protect against damage and to maximize productivity.R40+ yoke pipe vise with 2 1/2" pipe capacity is built on the same, sturdy tripod platform. Double-sided jaws allow for reversal before replacement. Ask for REED/RIDGID® brand interchangeable parts list for RIDGID® brand 460 and 40.
