## Questions & Answers

**Q: What are the dimention of the pin. I would like to try it on a Lift Master which has a 7/16" diameter clevis pin.**
A: clevis pin that came with the MM562 is 3/8" the pin lock is 7/16" drilling the gate bracket that galvanized will invite corrosion. What I did is to keep the clevis pin and replace the hairpin clips with a small lock that has same diameter as the hairpin clips

**Q: What key blank does this lock use? I will need to have more keys made. Thank you for your time.**
A: Sorry, I don't know.  2 keys were enough for us.

**Q: My brochure states this is lock needed for Mighty Mule 360.  Lock won't fit, dont know how to make larger holes.  Is there another lock?**
A: Lock fits the post mount but not the gate mount for me. I’ll have to drill the gate mount bracket holes larger for it to work.

**Q: It says twin pack, but quantity 1. how many locks come per package?**
A: Deceptively advertised as a twin pack but you only get ONE lock. JUST ONE. No TWIN anything.
