code? - ANS-Move in 1/four inch. Code is three/four in
After receiving an inspection document, one violation is door last force. After checking you
examine 50 lb of door force, is that this code? How do you are making it code compliant? -
ANS-Not code. Code is < 30 lb. To fix you need to modify the torque/pace of door operator
