Mamiya Press 6x7/6x9 Film Holder Light Seals Replace Kit

This is the Light Seals foam (backdoor gasket sponge and Mirror Cushion) replace kit for the Mamiya Press 6 x 9 Film Holder.

(Please note: This item is a custom kit, NOT a Mamiya brand-name part.)

When the original light seals become old, they can cause light leaks and backdoor rattling. By replacing them with new light seals, you will eliminate these problems.

2 foam kits are included. If you are not confident, you can use the first kit for practice, ensuring you can install it perfectly on the second try.

1. Remove the old light seals and clean up the residue with alcohol or benzine.
2. Take out the new light seal from the base paper.
3. Use a cotton swab or paint brush to rub alcohol or water on the adhesive (sticky) side. The alcohol or water delays adhesion and allows you time to position and adjust the seals.
4. Place the seals into the groove.
5. Use a flathead screwdriver to adjust the seals before the alcohol/water dries.
