Hello,
This is a series 1210 sgd-r25 door. I need to find a replacement for this lock and can't decide between the 82-211 and 82-214B, which look identical. Can you help?
Thank you, Lori
Hello! I agree, your mortise looks like it could be either the 82-211 or 82-214B.
The major difference between them is size. Please refer to the diagram for each product below and compare them to your original part. That should help you determine the best match.
Note that you will need to remove the original before you measure; it won't be possible to measure accurately without doing that first.
Please let us know if you had any follow up questions!
