Galvanized Marine Thimbles & Shackles

Galvanized Thimbles & Shackles — Rigging Hardware Add-Ons:

Enhance your custom rope splicing orders with durable galvanized marine hardware — built to reinforce rope eyes, improve connections, and protect against corrosion in marine environments. Whether you’re completing a dock line, mooring line, or specialty rigging project, these galvanized thimbles and shackles provide reliable performance and long-lasting service.

Galvanized Marine Thimbles:

Provide secure, long-lasting protection for your rope eyes with our marine-grade thimbles. Designed to fit your rope perfectly, these thimbles help prevent wear, chafing, and deformation where the rope loops around hardware. Ideal for extending rope life. Hot-dipped galvanized steel — corrosion resistant and suited for marine/ outdoor environments.

👉 Pick a Thimble That Matches That Diameter

 Match your rope’s diameter to the correct thimble size below for best performance and protection. Thimbles are sold by the rope size they are made to fit.

Rope Diameter	Thimble Size
⅛″ (3 mm)	⅛″ thimble
¼″ (6 mm)	¼″ thimble
⅜″ (10 mm)	⅜″ thimble
½″ (12 mm)	½″ thimble
⅝″ (16 mm)	⅝″ thimble
¾″ (19 mm)	¾″ thimble
1″ (25 mm)	1″ thimble
1¼″ (32 mm)	1¼″ thimble

⚓️ Pro Tip: If your rope is coated (e.g., vinyl), measure the coated outside diameter and use that measurement when matching to thimble size.

Galvanized Marine Shackles:

Galvanized screw-pin shackles connect rope terminations to hardware like thimbles, anchors, rings, or other fittings. Shackles listed here are typical galvanized anchor-type shackles with industry-standard working load limits for common marine and rigging applications.

Galvanized Marine Thimbles & Shackles — Sizes & Working Load Limits  

(Thimbles improve performance by protecting rope eyes and reducing abrasion; they are not rated with a load limit — they are used to support rigging integrity rather than carry loads directly.)

Hardware	Size	Working Load Limit (WLL)
Thimble	1/4″	Not Rated
Thimble	5/16″	Not Rated
Thimble	1/2″	Not Rated
Thimble	5/8″	Not Rated
Thimble	3/4″	Not Rated
Thimble	1″	Not Rated
Shackle	1/4″	~1/3 tons
Shackle	5/16″	~1/2 ton
Shackle	3/8″	~1 ton
Shackle	1/2″	~2 tons
Shackle	5/8″	~3.25 tons
Shackle	3/4″	~4.75 tons
Shackle	7/8″	~6.5 tons
Shackle	1″	~8.5 tons

⚓️ Pro Tip: Always verify exact WLL on manufacturer markings/datasheets for safe rigging use.

Hardware Features:

✔ Marine-Grade Protection: Hot-dip galvanized coating resists rust and corrosion — perfect for saltwater. Forged carbon steel with alloy pins. Heat treated.

✔ Reinforced Rope Eyes: Thimbles protect rope from wear and tear and help maintain secure eyes (terminations).

✔ Versatile Hardware: Shackles provide secure connection points for dock, mooring, and various rigging assemblies.

✔ Multiple Sizes: Choose from a broad range to fit your rope diameters and load needs.

 

Sizing & Compatibility Tips — Get It Right Every Time

Choosing the correct size hardware is critical for performance, safety, and longevity of rope terminations — especially in marine and load-bearing applications.

✔ Match thimbles to rope diameter for best protection and fit. The thimble groove must closely match the actual diameter of your rope — not too small and not too loose.

✔ Always measure the rope diameter before selecting a thimble size.

✔ Safety First: Thimbles themselves aren’t load-rated but help maintain rope strength and prevent wear that could lead to failure.

Whether you’re rigging cleats, launching anchors, or setting up dock lines, using the correct thimble size matched to your rope diameter ensures maximum strength and reliability.
