How to find the right Flag Hinges AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Flag Hinges

Handing
Order left- or right-hand flag hinges to match the side the door lifts off from. Flag hinges are handed, and the wrong hand will not lift off in the right direction.
Mounting style
Choose weld-on or screw-on leaves based on the door and frame material. Weld-on flag hinges need weldable steel, and screw-on types need enough material thickness for thread engagement.
Pin and material
Use stainless or plated steel with a fixed pin sized for the door weight. Flag hinges carry load in shear on the pin, so an undersized pin bends and the door drops.

What to avoid

  • Ordering mixed hands for a single door
  • Unplated steel in outdoor or washdown areas
