Adjustable Leg for Modular Workbench

A modular workbench is only modular if every component scales the same way. The Unior 990LA-US Adjustable Leg is the bench-frame component that lets a shop build a non-standard bench size or correct for a non-level floor; an adjustable-height leg that attaches to any 2600-series bench top and lets the install fine-tune working height to the mechanic and the floor.

How it works

The 990LA-US is a leg, not a complete bench frame. It threads into the bench-frame underside at the standard mounting point and adjusts via the threaded foot for fine height-tuning. The adjustment range covers small (millimeter-scale) corrections for floor unevenness and larger (centimeter-scale) corrections for working-height preference.

When to specify

Three install scenarios where the adjustable leg is the right fix:

1. Non-level floor. The bench top sits true on a flat floor; on a service-shop floor pitched toward a drain, the bench drifts off-true. The adjustable leg corrects per-corner without re-pouring the floor.
2. Short-mechanic primary bench. For mechanics shorter than 5’6”, the European standard 91 cm bench top runs slightly tall. The adjustable leg lets the install drop the working height a few centimeters to match.
3. Custom modular configuration. A shop building a non-standard bench (combining a 990TW wood top with a 990WD7 cabinet at a working height that doesn’t match a stock 2600-series bench) uses the 990LA-US to set the floor height.

For tall-mechanic shops that need to raise the bench rather than tune it, the Cabinet Risers 990WDU are the dedicated 60 mm raise component.

Specs

• Type: adjustable-height bench leg.

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 990LA-US is part of the modular bench system; same manufacturing chain as the bench tops and cabinets it supports.

Pro tip from our mechanics

Adjustable legs are an install-time decision, not a retrofit. Specify them at order time if the floor is known-uneven or the mechanic working the bench is shorter than average. Retrofitting adjustable legs onto a bench already loaded with cabinets and tools means tearing the bench down first.
