When the original light seals become old, it occurs light leaks and backdoor rattling.
It is time to replace the new Light seals, you do not have to worry about those problems any more.

Those are already cut, Ready to Use, You do not need to cut by yourself,

How many hours you should spend for measuring foam seal size and cut them if you do it by yourself?
Actually I spent 2 hours for measuring to make datas of cutting molds.

You can save time, this is no hassle and these are accurate size for Mamiya RB-67 camera body and 6x7 film back

Install this kit is not very difficult,
2 foam kits are included, you do not have to worry if you waste one.
If you are not so confident, you can use 1 kits for practice, you can install perfectly for the second time.



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 cotton swab or paint brush and rub alcohol or water on the adhesive (sticky) side.
The alcohol or water delays the adhesion and allows you time to position and adjust the seals.

4. place the seals onto the ditch.


5,6. Use flathead screwdriver and adjust the seals before the alcohol get dry.

Since the mirror is easy to get scratched,
please handle it with extreme care when you replace mirror cushion sponge.

I do not recommend you to replace this cushion unless you are an expert.
The flocked paper is covered this part and extremely easy to get torn. This cusion sponge is not included.

This kit fits to Mamiya RB-67 camera body and 6x7 film back, does NOT fit to the other camera or filmback
