Chain Link Line Rail Clamps, Galvanized - Multiple Sizes

Product Description

Galvanized Chain Link Line Rail Clamps (Boulevard Clamps) — Multiple Sizes

• Fast, Clean Brace Rails — Attach horizontal brace rail to line posts without brace bands or rail ends
• Uniform Alignment — Keeps mid-rail and bottom rail at a consistent height along the fence line
• Heavy-Duty Steel — Pressed, galvanized steel resists corrosion and jobsite abuse
• Two-Piece “Sandwich” Design — Clamps post and rail together with two carriage bolts (size varies by clamp)
• Multi-Use — Also handy for pipe-frame projects like greenhouses, kennels, backstops & tennis courts

Line Rail Clamps—often called boulevard clamps—make it easy to run mid-rails and bottom rails straight through line posts without extra fittings. Each two-piece clamp sandwiches the post and rail together with two carriage bolts, giving you a rigid, professional connection and a clean, uniform look across long runs.

Why Choose This

• Fewer parts — Replaces brace bands + rail ends at line posts
• Cleaner lines — Consistent elevation for mid/bottom rails
• Durable — Galvanized pressed steel for outdoor service
• Versatile — Works on fencing and other pipe-frame builds

Specifications

*Select bolt grade/finish to match your project and environment.

Installation

Position the two clamp halves around the line post and the rail. Insert the two carriage bolts and tighten evenly until snug—firm enough to hold alignment without crushing or ovalizing the pipe. Repeat at each line post to carry the rail straight through. For terminals/corners, use rail ends + brace bands instead of line rail clamps.

Buying Guide

• Where they go: Use on line posts for mid/bottom rails; do not use on terminal or corner posts.
• Clamp size: Match post O.D. and rail O.D. (see the Spec table). The “× 2″” size is for 2″ O.D. rail.
• Hardware: Two carriage bolts per clamp (sizes above). Washers/locknuts optional depending on spec.
• Finish choice: For color systems, choose color-coated line rail clamps to match Black/Green/Brown framework.

Frequently Asked Questions

What’s the difference between a line rail clamp and brace bands with rail ends?

Line rail clamps join the rail to a line post in one step. Brace bands + rail ends are used at terminals/corners to terminate the rail.

Are bolts included?

No. Order carriage bolts separately in the size noted for your clamp.

Can I use these for top rail?

They’re intended for mid and bottom rails. Top rail typically runs through loop caps on line posts and terminates at rail ends on terminals.

How tight should I make the bolts?

Tighten until secure but avoid deforming the pipe. Even torque on both bolts keeps the rail centered and square.

Do these work outside of fencing?

Yes—common in pipe-frame projects such as greenhouses, kennels, backstops, and court fencing.
