Secure 39mm Leica Mount Attachment

This Beseler jam nut fastens 39mm Leica mount lenses to cameras or enlarger boards. It suits photographers who need a dependable mechanical lock for screw-mount optics. The part number is 8095 and the condition is new.

Brass Construction Withstands Repeated Use

Machined from solid brass, the nut resists stripping and corrosion during frequent lens changes. Its 39mm thread engages cleanly with Leica-spec mounts, preventing play that can shift focus. The knurled edge allows hand tightening without tools.

Compatible With APO-Componon And Nikon Enlarger

The accessory fits APO-Componon lenses and Nikon 50mm, 75mm and 80mm enlarger optics. It also threads onto Beseler 23CII-XL lens boards. Buyers using bayonet-mount lenses or non-Leica thread pitches cannot use this nut.
