Wall / Bench Mount Clamp

A small-parts station; the corner of the shop where a wheel comes off a bike, a derailleur gets cleaned, or a bottom bracket gets pressed; needs a holding clamp, not a full repair stand. The full stand takes floor space; the small-parts work doesn’t need the lift. The Unior Wall / Bench Mount Clamp 1693.2-US is sized for that role: a fixed-mount clamp for the bench-corner workflow, with the easy-grip adjustment screw and pressure tuning that make it usable by professionals and home workshops alike.

How it works

The 1693.2-US mounts to a workbench edge or wall surface; fixed, not free-standing. The clamp jaws accept tubes from Ø24 mm to Ø32 mm (a range that covers most seatposts, fork steerers, and small frame elements). The jaw pressure adjusts via a hand-turned screw; no wrench required. The screw modifies both opening and closed pressure, so the clamp tunes to the diameter of the work piece without re-mounting.

Where it fits

Three workshop workflows where a fixed bench-mount clamp earns over a full repair stand:

1. Small-parts station. A bench corner dedicated to removed-from-bike work; wheel truing prep, derailleur cleaning, brake bleed bottle holding. The bench surface is already there; the clamp doesn’t take floor space.
2. Wall-mount alongside a stand. The bench-mount clamp’s wall-mount option creates a second working position alongside an existing free-standing repair stand for the bench mechanic.
3. Home workshop dedicated bench. A home workshop’s bench doesn’t always have room for a full repair stand; the 1693.2-US gives the bench clamp-and-hold work without the stand’s floor footprint.

For full bike-on-stand service, the Electric Repair Stand 2.0 and the manual Unior pro stands are the right tools. The 1693.2-US is the bench-mount partner to those stands, not a replacement for them.

Specs

• Mount: bench-top or wall-mount.
• Tube diameter range: Ø24 mm to Ø32 mm.
• Adjustment: hand-turn screw modifies jaw opening and pressure (no wrench needed).
• Use case: professional and home workshops.

Pairs with: the bench-corner stand body (1693.25) and the adjustable screw for shops that need replacement small-parts.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče, Slovenia, since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 1693.2-US shares the clamp engineering of the larger Unior pro repair-stand family; same hand-turn adjustment screw, same jaw-tube tolerances, sized for fixed-mount rather than free-standing service.

Pro tip from our mechanics

The 1693.2-US is one of those purchases that’s small enough to feel optional but earns its place by the third week. The decision is usually “where in the shop does the bench mechanic do the work that doesn’t belong on the main stand”; that location is where the 1693.2-US goes.
