Chain Link Gravity Hinge Sets by DAC Industries, Self Closing in Either Direction, Galvanized - Multiple Sizes

Product Description

DAC Industries Gravity Self-Closing Chain Link Gate Hinge Sets — Two-Way Swing

• Spring-Free Closing — Gravity mechanism closes the gate automatically with no springs to wear out
• Two-Way Operation — Swings in or out and returns to closed, ideal for pedestrian traffic
• Adjustable Close Force — Raise the bottom hinge to increase closing force and latch engagement
• Grade-Friendly — Self-rising action can compensate for slight slopes/uneven ground
• Hardware Included — Hinge set and mounting bolts for post and frame are in the box
• Galvanized Steel — Zinc-coated components built for outdoor, professional grade use

DAC Industries gravity hinge sets use a self-rising design: when the gate opens, the bottom hinge lifts the frame slightly out of plumb; release the gate and gravity brings it back to closed—smoothly, reliably, and without springs. This two-way version lets the gate swing both directions and is a favorite for residential walk gates and light commercial entrances that see frequent use.

Why Choose This

• Low maintenance — No internal springs or hydraulics to adjust or replace
• Consistent closing — Simple geometry delivers repeatable, field-proven performance
• Installer-friendly — Intuitive setup; closing force adjusts by bottom-hinge height
• Versatile — Compatible with common chain link latches (e.g., auto-latch, butterfly)

Specifications

Installation

Dry-fit the top and bottom hinges on both the gate post and the gate frame. Install with hinge pins pointing up. Square the frame, fully seat the hinges, and tighten hardware. To increase the closing force and ensure reliable latching, mount the bottom hinge slightly higher so the gate lifts as it opens. For installations on mild slopes, use the self-rising action to maintain bottom clearance. Test swing in both directions and fine-tune the bottom hinge height as needed.

Buying Guide

• Two-way vs. one-way: Choose this two-way set when you want in-and-out swing. For single-direction swing (e.g., certain safety/pool layouts), use the DAC one-way gravity hinge set.
• Selecting sizes: Match the frame O.D. (1-3/8″, 1-5/8″, or 2″) and the post O.D. (2″, 2-1/2″, or 3″). See combinations in the specs above.
• Latches: Works well with self-latching butterfly latches and DAC Auto-Latch kits for secure closure after every pass-through.
• Use case tips: For heavier or wide gates, ensure solid post footing and proper latch alignment; increase bottom-hinge rise to boost closing energy.

Frequently Asked Questions

How do gravity hinges close the gate without springs?

The bottom hinge lifts the gate slightly when opening; gravity brings it back down as you release, returning the gate to closed.

Will these work on a slight hill or uneven grade?

Yes—self-rising geometry can compensate for mild slopes while keeping the bottom clearance consistent.

Do these hinges swing both directions?

Yes—this model is the two-way version, so the gate can swing in or out and still self-close.

What size combinations are available?

1-3/8″ × 2″; 1-3/8″ × 2-1/2″; 1-5/8″ × 2-1/2″; 1-5/8″ × 3″; 2″ × 2-1/2″; 2″ × 3″ (frame O.D. × post O.D.).

Is all the mounting hardware included?

Yes—the hinge set includes the post and frame hinge parts plus the necessary bolts.

Which way should the hinge pins face?

Install with pins pointing up for greater security.

Comparison

• Two-Way Gravity Hinges (this item): Spring-free, low-maintenance self-closing; swings in/out; adjustable close force via bottom-hinge height.
• One-Way Gravity Hinges: Same spring-free mechanism but restricts swing to a single direction—often preferred for controlled-egress applications.
• Spring Hinges: Tension-adjustable and compact, but use internal springs that can fatigue over time.
• Hydraulic Closers: Highly tunable close speed/force; best for ornamental/pedestrian gates; higher cost and complexity than gravity sets.
• Strap Hinges (non-closing): Simple and economical but do not self-close without an added closer.
