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

Stainless Steel Finish

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 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 Stainless Steel.

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 hinges
  • stainless steel spring 
  • fasteners
  • tensioning tool for the spring (can also use your own 1/4" socket wrench)

About the spring

Made of stainless steel, 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

Hardware Tips

360 Yardware strives to offer a full selection of heavy duty wood gate hinges and strap hinges for gates. We carry garden gate hinges that work for smaller gates, ball bearing gate hinges for medium sized gates, and for heavy driveway gates we have stout heavy duty driveway gate hinges in dark bronze that can support 250 pounds per pair. Those customers searching for pool gate hardware can use our spring loaded hinges for gates, also known as self-closing hinge. Outdoor gate hinges come in different materials so you’re sure to find what you need: iron gate hinges, bronze hinges, and stainless steel hinges for coastal locations. A wide variety of finishes are available, including black gate hinges, oil-rubbed bronze, brushed stainless steel, and satin nickel.

Gate hinges, even heavy duty gate hinges, can add architectural complement to your gate. Strap hinges and our “H” hinges are visible when the gate is closed, so the hinge adds to the look. Butt hinges, on the other hand, are not visible on the face of the gate.

To help you make your gate hinge decisions, we’ve compiled a blog entry that discusses each aspect of heavy duty gate hinges, so that you can choose the right hinge for your job.
