Brand Reviews
Crosby HG-228 — When It Absolutely Has to Hold
⭐ 4.8/5 | Crosby turnbuckles feature superior forging, hot-dip galvanizing (vs zinc plating), and individual proof test certificates. The thread engagement is smooth and consistent — important when you’re adjusting tension 30 feet in the air on a scaffold.
Pros: • Hot-dip galvanized (superior corrosion resistance) • Smoothest thread engagement • Individual proof test cert • Crosby reputation
Cons: • 2-3× the price of imports • Can be hard to find in small quantities
Chicago Hardware — Best Value American-Made
⭐ 4.5/5 | A solid, American-made turnbuckle at a fair price. The zinc plating is adequate for indoor and mild outdoor use. A good choice when you need quality without Crosby’s premium.
Pros: • American-made • Good quality • 40% cheaper than Crosby
Cons: • Zinc plating (less corrosion protection than hot-dip galv) • Thread slightly rougher than Crosby
E-Rigging — Budget Import
⭐ 4.2/5 | Chinese-made turnbuckles at 1/3 the price of Crosby. Acceptable for non-critical applications like fencing, garden structures, and decorative cable railings. Not recommended for overhead loads or structural applications.
Pros: • Cheapest by far • Good for non-structural use • Easy to buy in bulk
Cons: • Inconsistent forging quality • Thread engagement can be rough • Zinc plating thin • Not recommended for critical applications
Turnbuckle Configuration Guide
Jaw & Jaw: Most versatile — connects to eyebolts, shackles, or other hardware.
Eye & Eye: For connecting to hooks or clevises.
Hook & Hook: Quick connect/disconnect — common in stage rigging.
Jaw & Eye / Eye & Hook: Mixed configurations for specific applications.
Pipe body (closed body): Prevents foreign objects from jamming threads. Required in food processing and cleanroom environments.
Recommendation
Structural / rigging: Crosby HG-228 — no compromise on safety. General industrial: Chicago Hardware — American quality, fair price. Decorative / fencing: E-Rigging — adequate for non-load-bearing applications.

Frequently Asked Questions
What size turnbuckle do I need for a guy wire?
Size is determined by the required tension load. Calculate the maximum force on the guy wire including dead load, wind load, and safety factor. Select a turnbuckle with a WLL exceeding this value. Common sizes: 1/4-inch (500 lbs WLL), 3/8-inch (1,200 lbs), 1/2-inch (2,200 lbs), 5/8-inch (3,500 lbs), 3/4-inch (5,200 lbs), and 1-inch (10,000 lbs). For antenna guy wires, a 3/8 or 1/2-inch turnbuckle is usually sufficient. Always verify the take-up length (adjustment range) meets your needs.
What is the difference between drop-forged and cast turnbuckles?
Drop-forged turnbuckles are made by hammering heated steel into a die, aligning the grain structure for maximum strength. They are rated for overhead lifting and structural applications. Cast turnbuckles are made by pouring molten metal into a mold — they are cheaper but have a more random grain structure and lower impact resistance. Cast turnbuckles should only be used for non-critical applications like fence tensioning. Never use cast turnbuckles for rigging, guy wires, or any safety-critical application.
Should I lubricate turnbuckle threads?
Yes. Apply anti-seize compound or light machine oil to the threads during installation and during periodic maintenance. Without lubrication, threads corrode and seize — making future adjustment impossible and requiring cutting the turnbuckle off. In marine environments, use a marine-grade anti-seize to prevent galvanic corrosion between dissimilar metals. After lubrication, always install lock nuts or safety wire to prevent the turnbuckle from vibrating loose.
