For mounting adjustable arms when the desk edge is thicker than the rest of the worksurface (common with bullnose edges or thicker laminate trim). The Mounting Spacer fills the gap so your mechanism sits flush.
Compatible with all Active Ergonomics arm mechanisms. Choose your track size to match your mechanism, then select the spacer thickness needed to clear your desk edge.
Sizing
- Track Size — match your mechanism (17″ or 21″)
- Thickness — 1/4″, 1/2″, 3/4″, or 1″ — choose the difference between your edge thickness and the flat under-surface thickness
