No matter what you have in mind, when you're searching for an individual square ring or a pack, then look no further than our great range at Haifan Rigging.
This marine grade square ring (often called a square loop or rectangular loop) is a heavy-duty, four-sided metal fastener engineered to resist severe rust and saltwater corrosion. Its perfectly straight sides are specifically designed to keep wide webbing, belts, or straps lying completely flat, preventing the material from bunching, twisting, or shifting under tension. Like other true marine hardware, it is manufactured using premium Type 316 stainless steel.
Key Characteristics
The Material: Made from 316 Stainless Steel to withstand continuous exposure to saltwater, harsh weather, and UV rays without pitting or rusting.
The Shape: Unlike round rings, the flat edges ensure that any strap running through it maintains uniform tension across its entire width.
Construction: Most marine-grade square rings are solidly welded and polished smooth to eliminate rough edges that could fray or cut fabric straps.

Common Applications
Scuba Diving Harnesses: Slid onto heavy nylon webbing to act as rigid attachment points, weight keepers, or connection loops for gear.
Boat Cover & Bimini Straps: Used to secure and tension marine canvas tops, boat covers, and tie-down straps flat against the boat hull or rails.
Heavy-Duty Outdoor Gear: Integrated into premium backpacks, cargo tie-downs, and animal harnesses that are frequently exposed to rain, mud, or coastal air.
