Replacement Clamp Jaw Covers 96mm

Replaceable rubber jaw covers are the wear part on every Unior stand clamp; the rubber takes the daily grip-and-release work, picks up grit and frame cleaner residue, and eventually wears thin or tears at a corner. The 96 mm Replacement Clamp Jaw Covers (Unior 1693.11) are the cover size sized for the older square-style jaw geometry on cam-style 1693.1 / 1693.1S clamps with the 90 mm jaw height; the wider taller jaws found on long-serving cam clamps from the 1693 family's earlier production runs.

When the rubber wears, you replace the rubber; the clamp itself stays. The covers slip onto the existing jaws without tools and lock into the same retention geometry the original factory covers used. The clamp goes from “showing its age” to “freshly bedded” in the time it takes to swap them in.

Why fresh covers matter

A worn jaw cover doesn't grip the frame tube the way a fresh one does. The rubber compound is the surface that holds the bike under torque; once the rubber is glazed, hardened by frame cleaner, or torn through to the metal beneath, the clamp's hold on the bike is compromised. For carbon frames, an over-tightened clamp on worn covers is the failure mode that ends with a cored seat tube; for aluminum frames, it's the route to a clamp-shaped dent. Fresh covers protect both the bike and the clamp.

Sizing: confirm before you order

This is the 96 mm cover for the older square-style cam-clamp jaw geometry. Two other cover sizes are available for different Unior clamp variants:

• 70 mm covers fit the Pro Shop Clamp (1693.1Q) and the 70 mm-jaw variants of the 1693.1 / 1693.1S cam-style clamps.
• 57.2 mm covers fit the Master Shop Clamp (1693.1M) with the shorter round-jaw geometry.

Measure your existing covers (or the bare jaw, if your stand is running with a shop rag in place of covers) before ordering; the three sizes are not cross-compatible. The 96 mm cover is the right buy if your clamp has flat-faced square jaws that measure 90 mm tall.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The continued availability of the 96 mm cover for older cam-clamp jaws reflects Unior's long-service-life design assumption; cam-style clamps on shop walls from a decade ago still get rubber-cover service from the same SKU family. A stand bought in 2014 still gets its consumable parts in 2026.

Pro tip from our mechanics

If you're not sure whether your clamp uses the 96 mm cover or the 70 mm cover, the visual test is the jaw face: square-jaw clamps with a flat-faced rectangular profile and 90 mm jaw height use the 96 mm cover. Round-jaw or shorter-jaw clamps use a different cover. For shops running multiple clamp generations on the bench, keeping a small inventory of all three covers (70 mm, 96 mm, 57.2 mm) is the practical way to never get caught mid-job with a torn cover and the wrong size in stock.
