The H-Lift Zinc Plated Quick Link is a versatile steel chain connector featuring a threaded gate, designed to provide secure, semi-permanent connections for chains, ropes, and hardware assemblies.
The Zinc Plated Quick Link is an essential piece of hardware designed for the rapid repair, extension, or connection of low-carbon chains. Featuring a smoothly threaded sleeve that creates a fully closed loop when tightened, it provides a significantly more secure and stable connection than standard spring-loaded snap hooks or carabiners.
Features a smoothly threaded sleeve (nut). Once tightened, it acts as a fully closed chain link, eliminating the risk of accidental roll-out that can occur with spring-loaded gates.
Coated in a bright zinc plating (electro-galvanized) to provide a reliable protective barrier against rust, making it ideal for general outdoor, industrial, and utility environments.
Designed to be tightened down firmly with a wrench for permanent or semi-permanent connections. It is the safest, most reliable field-expedient way to repair a broken general-purpose chain link.
The standard oval shape is perfect for joining lengths of chain, attaching cables to eye bolts, securing playground swing chains, hanging heavy lighting fixtures, and connecting trailer safety chains.

Types, Design, Installation & Safety Precautions
A Quick Link (also known as a Rapid Link or Maillon Rapide) is a mechanical connecting link used to join two chains, attach cables, or close a loop securely. It functions similarly to a carabiner but uses a threaded sleeve (nut) to close the opening rather than a spring-loaded gate.
Because the threaded sleeve can be tightened with a wrench, quick links provide a much more secure and permanent connection than a standard snap hook, while still allowing for disassembly when needed.
Quick links come in various geometric shapes to suit different directions of pull and connection requirements:
Design: The most common type, resembling a standard chain link with a threaded opening.
Use: Ideal for joining two lengths of chain or attaching chain to eye bolts. It is designed for loading along the major axis.
Design: Features a significantly wider gate opening than the standard oval type.
Use: Necessary when attaching to larger diameter bars, pipes, or fittings that wouldn't fit through a standard opening.
Design: Triangular shape designed to accept webbing or straps on the flat side.
Use: Commonly used in webbing assemblies, parachuting, or connecting three-way loads.
Design: Resembles a pear; one end is narrower than the other.
Use: Used when connecting two components of different sizes or allowing movement for multiple small connectors at the wide end.
Quick links are robust connectors used in a wide variety of industries:
The security of a quick link depends entirely on how the nut is tightened. For temporary use, "finger tight" may suffice. For permanent or critical applications, the nut must be tightened with a wrench.
Never load a quick link if the nut is not fully closed. The structural integrity of the link relies on the closed loop. If the threads are visible or the nut is open, the link is significantly weaker and will fail under load.
