Negative Supply Pro Mount MK2 Leg Extension Kit

The Negative Supply Pro Mount MK2 Leg Extension Kit is a simple but essential upgrade designed to make existing Pro Mount MK2 systems compatible with the newer 4x5 Light Source Pro. By raising the Pro Mount higher above the light source, these extended feet provide the necessary clearance while also adding stability and support to your scanning setup.

System Compatibility Notes

This accessory is specifically designed for users who already own a Pro Mount MK2 and wish to use it with the Negative Supply 4x5 Light Source Pro. The original Pro Mount MK2 was designed around the older 5x7 Light Source Pro, where the mount rested directly on the corners of the light source. The newer 4x5 Light Source Pro has a different design and requires these taller standoffs to provide the correct clearance. This kit is not required when using older 5x7 Light Source Pro models.

Why We Like It

Negative Supply systems are designed to work together with very tight tolerances, and this kit is a perfect example of that. Rather than replacing an entire Pro Mount, existing owners can simply fit these upgraded feet and continue using their setup with the latest light source. The larger rubber feet also add a welcome boost in stability, particularly when working with heavier scanning rigs.

William W. ★★★★★

I've been using these extension legs for a few weeks now, and the way they click securely into place is a massive improvement over my previous setup. My scans are noticeably more stable, and it's made working with taller film holders much less awkward.

Adam B. ★★★★★

The extra height this adds to the Pro Mount MK2 is just right for my workflow, and the locking mechanism clicks into place with zero wobble. I’ve been using it for a few weeks now and it’s made scanning so much more comfortable.

Evelyn ★★★★★

I was worried the kit wouldn't fit my setup, but the compatibility with the Pro Mount MK2 is spot-on. Now I can finally get the copy stand low enough for my larger prints, and the whole thing feels rock solid.
