LOCKJAWZ HD-T-Post Insulator Blk-BAG OF 20

When a standard insulator just isn't enough, the LockJawz HD T-Post Insulator steps up. The original LockJawz design—now in a heavy-duty version—delivers more grip, more versatility, and more durability than conventional T-post insulators. Thicker and wider than the competition at 1" versus the typical 5/8", this insulator grabs the post with authority and stays put under the pressure of high tensile fencing.

What sets LockJawz apart is its 6-position 360° mounting system. Whether you need the wire on the front, back, or side of the post, LockJawz gives you the flexibility to position it exactly where your fence design demands—without extra hardware or workarounds. It works equally well as an in-line insulator or a corner insulator on T-posts, and can also be used on wood posts with 2.5" barbed staples (sold separately).

The intuitive one-piece design means no pins to lose in the field, and the easy weave-in wire installation gets your fence built faster. Molded from UV-stabilized automotive-grade high-density co-polyethylene and made in the USA, these insulators are built to outlast the fence they're protecting.

Features

Heavy-Duty Grip
Thicker and wider at 1" (vs. standard 5/8") for a stronger, more secure hold on the post under high tensile pressure.

6-Position 360° Mounting
Mount the wire in any of 6 positions around the post for maximum fence design flexibility.

Dual-Use: In-Line & Corner
Functions as both an in-line T-post insulator and a corner insulator—one product for multiple applications.

Wood Post Compatible
Use on wood posts with 2.5" barbed staples/U-nails (sold separately) for true multi-post versatility.

No Pins to Lose
Intuitive one-piece design eliminates loose pins that get dropped and lost during installation.

Easy Weave-In Wire Installation
1/4" material opening makes threading wire fast and straightforward in the field.

Increased ARC Guards
Enhanced arc guards reduce the risk of voltage leakage between wire and post.

UV-Stabilized Automotive-Grade Co-Poly
Built from premium materials that resist UV degradation and hold up in all weather conditions.

Made in the USA
Patented design (Pat. No. 10,358,840) manufactured domestically for consistent quality.
