KIT: 3 Heavy Duty Ball-Bearing Hinges + Gate Closer Spring

Stainless Steel and Powder-Coated Black 

4-1/2" x 4-1/2" Square Corners (Set of 3)

This kit will allow you to hang the gate with solid, 4-1/2" x 4-1/2" stainless steel hinges (black finish) and then install the spring to help the gate close.

Ball-bearing hinges are excellent for heavier doors and gates. The ball bearings allow an easier swing and will help prevent the sag that using an inadequate hinge sometimes causes.

This 4-1/2" stainless steel ball-bearing hinge has a stainless steel pin. Fasteners are included. #12 x 1-1/4" size. The finish is Satin Black.

A set of three holds a weight of 150lbs. Mounting screws included. Made of Stainless Grade 302/304. These are commercial-grade hinges.

Kit includes:

  • 3 - 4-1/2" x 4-1/2" stainless steel ball-bearing (black finish)
  • stainless steel spring (black finish)
  • fasteners
  • tensioning tool for the spring (can also use your own 1/4" socket wrench)

About the spring

Made of stainless steel and coated in a black finish, this gate spring will push the gate back closed. You install one bracket to the gate and one to the post (see images below). The spring is always installed on the side of the gate that it swings toward (the side of the gate with the hinges showing) so that it can push the gate closed. Note in the photo below how the spring is installed upper-right to lower-left. The spring always needs to be oriented with the tensioning knob on top-right. 


Spring Dimensions:

  • 13-1/2" overall length
  • Spring measures 10-1/2" long x 1-1/8" diameter
