Turnbuckles: The Unsung Workhorse of Tension and Design
par Maddison Mellem sur Jul 09, 2025Whether you're reinforcing a timber truss, bracing a pergola, or adding tension to a decorative feature, turnbuckles are the silent strength behind secure, well-built structures. At Old West Iron, we forge turnbuckles with both utility and aesthetics in mind—offering designs that perform under pressure and look good doing it.
What Is a Turnbuckle?
A turnbuckle is a mechanical tensioning device used to adjust the length and tension of rods, cables, or threaded assemblies. It consists of a central metal body with two threaded eye bolts, jaw ends, or hook ends screwed into each side—one with right-hand threads, the other with left-hand threads. When you rotate the body, it draws both ends inward, increasing tension.
It’s a simple concept—but when executed in forged iron, it becomes an essential part of both form and structure.
Common Uses for Turnbuckles
Turnbuckles are used anywhere controlled tension is needed. At Old West Iron, we see them most often in:
-
Timber frame trusses
-
Pergolas and pavilions
-
Decorative cross-bracing in rustic and industrial interiors
-
Furniture reinforcement
-
Gates, railings, and barn hardware systems
Pair them with our threaded rods or clevises to complete a custom tension rod system tailored to your build.
Built for Heavy Duty and Heavy Style
Old West Iron’s turnbuckles are forged with durability and design in mind. Unlike the zinc-coated imports you’ll find in hardware stores, ours are:
✔️ Hand-forged or cast from solid steel
✔️ Offered in multiple sizes and configurations (eye/eye, jaw/eye, hook/eye)
✔️ Available in heritage finishes—black, rusted, raw, sealed
✔️ Compatible with square head threaded rod systems
✔️ Designed for exposed architectural use
They're equally at home inside a barn, outside on a pavilion, or featured as part of a decorative industrial build.
How to Install a Turnbuckle
-
Connect threaded rods or tension members to both ends (one right-hand thread, one left-hand).
-
Anchor both sides securely to your structure.
-
Turn the center body to draw the two ends in and increase tension.
-
Lock in place with jam nuts or cotter pins, if needed.
