Fast-acting clamps are the workhorses of most shops. Easy to use, light, versatile and fast adjusting, they handle 90% of clamping needs. With a non-slip spring-loaded tailpiece for instant adjustment, they are ideal for fast assembly work.
These heavy-duty clamps are larger and more rigid than the standard-duty FA clamp.
3 1/2" throat depth, 1" face width, and a 5/16" × 1" spring-steel bar with two clutch plates. The screw has rolled threads. Load limit of 775 lb.
