The Simpson Strong-Tie PGT1.5Z-R Pipe Grip Tie is a fence connector designed to attach wood fence rails to metal fence posts. This is a pipe grip tie designed for wood-to-metal fence rail connections in new fence construction and fence repair. Model Number PGT1.5Z-R fits a 1-1/2 inch nominal pipe with a 1-7/8 inch outside diameter, giving you a practical way to keep the look of a wood fence while using longer-lasting steel posts behind it.

Where this connector earns its keep is simple: metal posts typically outlast wood posts, especially in ground-contact fence work where rot is the usual failure point. The PGT1.5Z-R wraps the post and gives you mounting ears on each side so the wood rail can be fastened directly to the connector. That means you get a solid rail-to-post connection without trying to notch, toe-screw, or improvise around a round pipe.

This model is made from 12-gauge steel, which matters because a fence connector takes repeated load from wind, gate movement, and seasonal wood movement. The heavier material helps the tie keep its shape once installed, and the ZMAX coating adds corrosion resistance for exterior conditions and treated lumber contact. If you are building or repairing a fence that needs to stay straight and hold up outdoors, coating and steel thickness are not throwaway specs here.

The Simpson Strong-Tie PGT1.5Z-R Pipe Grip Tie is also built to make installation straightforward. The tie installs on vertical pipes and tightens with one supplied 1/4 inch hex-head bolt. Rail attachment uses four 1/4 inch by 1-1/2 inch Strong-Drive SDS Heavy-Duty Connector screws, which are not included. That layout gives you a repeatable install method, which is helpful when you are setting multiple posts and want consistent rail alignment down the fence line.

Another useful detail is that the flanges can be field-bent one time to fit corner and angled conditions. That makes this connector more than just a straight-run bracket. It can help when you are tying into a 90 degree corner, working around a 45 degree change in direction, or replacing a damaged wood post in an existing fence where perfect geometry is not happening. Strong-Tie also notes using three to four PGT ties per pipe and lining up to stringline for a clean finished run.

In practical terms, this connector is for fence builders, remodelers, property maintenance crews, and serious DIY users who want the durability of steel fence posts without giving up wood rails and wood pickets. If your goal is a stronger fence structure with less post rot and fewer callbacks, this is the kind of small hardware choice that makes a real difference over time.

Simpson Strong-Tie PGT1.5Z-R Pipe Grip Tie solves the wood-post rot problem the smart way

If you want the look of a wood fence but trust steel posts more than buried wood, this connector is the clean answer.

• Who it's for: Fence builders, repair crews, and homeowners upgrading from wood posts to metal pipe posts.
• Why it stands out: 12-gauge steel, ZMAX corrosion resistance, and a design that lets you fasten wood rails directly to round metal posts.
• Worth knowing: You get the tie and bolt, but not the rail screws, so plan on the correct 1/4 inch x 1-1/2 inch SDS connector screws before you start.

• What size pipe does this tie fit? It is designed for 1-1/2 inch nominal pipe with a 1-7/8 inch outside diameter.
• Can it be used on fence corners or angled runs? Yes. The flanges can be field-bent one time to fit corner and angled conditions.
• What kind of project is this connector made for? It is made for fencing, specifically attaching wood fence rails to metal fence posts in new construction or repair work.
• Are the rail screws included? No. The tie uses four 1/4 inch x 1-1/2 inch SDS Heavy-Duty Connector screws for the rail attachment, and those are sold separately.
