This is serious commercial door hardware.

The Marks USA M9900 is a rim-mounted panic exit device – that's the kind of push bar you see on the inside of store or office doors for safe, quick exit.

It's built tough for high-traffic areas and comes with a lifetime warranty, which tells you how durable it is.

It's available in different lengths (like 36 or 48 inches) to fit various door widths.

Important note: This listing is typically for the exit device itself (the horizontal push bar and internal mechanism).

The trim – which includes things like the outside pull handle, key cylinder, etc.

– is usually sold separately, so you can choose the style you need.

This is professional-grade hardware meant for builders, facility managers, or business owners installing or replacing door hardware to meet safety codes.
