TechTips: 4 inch hinges

Things to consider

• .129” thick standard weight – Used for 1 3/8” & 1 ¾” doors
• Heavy Weight RARE to Not Available
• Standard 5/16” backset on frames and ¼” on doors

Red flags

• Many models are Non-Templated (get model # and Mfr.)
• (Zig Zag Pattern is rarely templated – No Drilling or Tapping Possible)
• Watch out for radius corners
• Different radius corners available (1/4” & 5/8” Radius)
