Accessories

Brief description

The RUWI vertical clamp with adapter plate secures your workpiece from above—for a 20-mm hole pattern. The round adapter plate (Ø 140 mm) is secured to the grid with two stainless steel clamping bolts (Ø 20 mm, hex socket screw SW 6): two anchor points keep the clamp from twisting. You can freely position the pressure point via the plate’s elongated hole, even slightly offset.

The stroke compensation accommodates material thicknesses up to 40 mm, with 35 mm of that range covered automatically without the need for readjustment. With a length of 244 mm, the clamp easily spans panels, frames, and individual parts. If you need more clamping height for particularly thick components, place the 50 × 50 adapter block underneath.

The horizontal clamp with adapter plate presses against a stop on the side. If you need the vertical clamp without an adapter plate—using a clamping bolt directly—the vertical clamp for the 20-mm hole pattern is the sleek solution; the positioning bracket serves as a fixed counterhold. You can find additional clamping accessories in the lift table system.

Possible applications

Secure workpieces from above – for the 20-mm hole pattern
Round adapter plate (Ø 140 mm) with a slot – position the pressure point freely and slightly offset
Two stainless steel clamping bolts (20 mm diameter) – secure, non-rotating hold
Stroke compensation up to 40 mm, of which 35 mm is automatic without readjustment
Can be combined with the 50 × 50 adapter block to increase the clamping height for thick components
