The Destaco 847-U is a new, pneumatically actuated hold-down toggle clamp from Destaco (a Stabilus Company), part number confirmed on both the cylinder endcap and original manufacturer packaging (PN: 847-U, Job# 15810383, dated 03/24/2026). The unit integrates a double-acting pneumatic cylinder (max 10 bar / 145 PSI, stamped directly on the cylinder end) with a heavy-duty toggle mechanism mounted to a machined aluminum and zinc-plated steel base, providing powered clamping and unclamping for fixture and assembly automation. The 847-U delivers a 94° bar opening arc with 2.25 in. of clearance height under the bar, utilizes 1/4 in. NPT air ports (blue push-in fittings visible on the cylinder), and the hold-down bar is stamped "24.7-U" indicating the standard adjustable U-bar spindle assembly; two lock washers are included. Typical applications include welding fixtures, assembly jigs, and robotic cell workholding where consistent, repeatable pneumatic clamping force is required without manual operator input.
