Hinges (industrial) Information



Industrial hinges are jointed devices that allow an attached part, such as a door or window, to swing.  




  • Butt hinges - Butt hinges are composed of two plates attached to abutting surfaces of a door and cabinet and joined by a pin.  Both leaves of the hinge are mortised (cut) into the edge of a door and frame.How to Select Hinges (Industrial)
  • Half-mortised hinges - Half-mortised industrial hinges are butt hinges where only one of the leaves is mortised (cut) into the door and frame.
  • Torque friction hinges - Torque friction hinges hold doors open and closed at pre-set, detent positions without secondary mechanical supports.  Adjust (dampen) the door swing to your specifications.  Models may include constant torque friction hinges and adjustable torque friction hinges.
  • Concealed hinges - Concealed hinges are any hinges that do not show from the outside of the cabinet.  Concealed hinges offer a smooth, unbroken cabinet surface.  The radius of the moveable leaf swings the door out and clears the cabinet frame.
  • Continuous (piano) hinges - Piano hinges are composed of two continuous leaves of material.
  • Knife hinges - Knife hinges are shaped like scissors. One half of hinge mounts to top edge (or bottom edge) of door. Other half mounts to horizontal cabinet member directly above (and below) door.
  • Latch hinges - Latch hinges make excellent lid or door latches, or easily removable hinges.
  • Overlay hinges - Overlay hinges are used for a door that sits in front of the cabinet and covers or overlays a portion of the cabinet or face frame.
  • Pin hinges - Pin hinges pivot on a single point. They offer a very low profile, as only the pivoting knuckle is visible from the outside of the cabinet.
  • Quick release hinges - Quick release hinges are used to easily remove a door, can be mounted in any position, and require no tools.
  • Slip joint (flag) hinges - Slip joint hinges offer quick, easy, and economical door removals.  Concealed type industrial hinges have two parts fastened together by slipping one half on the other and then tightening a screw.
  • Spring hinges - Spring hinges allow doors to close automatically or be held in the open or closed position.
  • Spring pivots - Spring pivots are mortised into the heel of a door and fastened to the floor and head with pivots.
  • Inside stop hinges - Inside stop hinges normally operate from the 0° or closed position towards the open position, stopping at 90°.  Some manufacturers may furnish special stop angles.
  • Outside stop hinges - Outside stop hinges normally operate from the 180° or flat, open position, towards the closed position, stopping at 90°.  Some manufacturers may furnish special stop angles.
  • Strap hinges - The strap hinge consists of two unequal hinge leaves where one leaf is longer and narrower than the other. The typical three-knuckle hinge is comprised of a larger center knuckle and equal and knuckles. The larger leaf will offer more of a mounting surface. Strap hinges are usually manufactured in heavier gauges with standard hole placements.

  • Weld-on hinges - Weld-on industrial hinges require welding to be mounted.
