6mm Spacer Block for QRC
A low cost spacer that allows sliding Quick Release clamp on Ultimate M upper rail. Normally the clamp can be only attached to the end. This spacer allows the clamp to be moved anywhere on the rail.
Compatible with: QRC-40A, QRC-50mm and QRC-65mm.
The 6mm spacer is now discontinued. Purchase the new QRC 40 L clamp (F2102) instead.
