Chicago Hardware Lag Hook — Left & Right Hand Thread
Chicago Hardware Lag Hook — Left & Right Hand Thread
The Chicago Hardware Lag Hook is a foundational component in tree cabling and bracing systems. This strong J-bolt with lag thread is designed to be driven directly into the tree, providing a secure anchor point for steel cable. Meets or exceeds standards for arborist cabling applications, and bright plating provides corrosion resistance for long-term performance in the field.
Available in both left-hand (LH) and right-hand (RH) thread configurations, and in four diameters from 1/4" to 5/8" — select the size appropriate for your cable diameter and tree species. All versions vary in length: 1/4" is 3-1/2" long, 3/8" is 4-1/4" long, 1/2" is 6" long and 5/8" is 7" long.

- Available in left and right hand thread for proper cable termination
- Four diameter options to match your cable size
🔥 Quick Decision Guide
- Best For: Installing tree cabling and bracing systems requiring a lag-threaded anchor point in the tree
- Not Ideal For: Dynamic or high-load rigging applications — designed specifically for static tree support cabling
- Skill Level: Certified arborists and technicians trained in tree cabling installation
- Use Case: Anchoring steel cable to a tree as part of a supplemental support system
- Why Choose This: Meets arborist standards, bright plated for longevity, available in both thread directions and multiple diameters
- Compare To: Eye bolts (through-bolt installation, more invasive but stronger); screw-in eye hooks (lighter duty)
Frequently Asked Questions
When do I need left-hand vs. right-hand thread?
In a cabling system, one end of the cable typically uses a left-hand threaded fitting and the other uses right-hand thread. This allows the turnbuckle or tensioning device to tighten both ends simultaneously by rotating in one direction without loosening either anchor.
How do I choose the right diameter?
Match the lag hook diameter to your cable diameter. Common pairings: 1/4" hook for 1/4" cable, 3/8" hook for 5/16" or 3/8" cable, 1/2" hook for 1/2" cable. When in doubt, consult ANSI A300 cabling standards or contact us.
