rectangular ring

a bagmaking essential

Rectangular rings are commonly used in bags, particularly in the construction of straps and handles. These rings play a crucial role in the functionality and/or aesthetics of bags.

These rings can be used in various bag styles, including backpacks, tote bags, shoulder bags, and more. They provide a secure and stylish way to attach and adjust straps, making them a versatile component in bag design.

A rectangular ring allows a strap or belt to move freely without the strap bunching together. Thus it is often used together with a strap slider. Apart from that, it can also be used as a handle connector.

It is also referred to as: square ring, connector ring or single loop slider, with the last two terms being more of a generic term for rings of various shapes.

size matters

Rectangular rings come in various sizes and dimensions. Common sizes range from 15 to 50mm (1/2 inch to 2 inches) in width.

When you buy a rectangular ring, the size that is indicated refers to the inner width of the ring. This is the most important measure since you have to match it to the width of the strap you intend to use.

Question: How much tolerance is acceptable for a good strap – rectangular ring fit?

Answer: A deviation up to 2mm both up or down is perfectly acceptable for a good fit. So e.g. a strap of between 36-40mm will usually fit into a 38mm rectangular ring. More space will make your strap susceptible to twisting, less space will make it almost impossible to feed through.

Question: Is the height important?

Answer: Not really. Whether you use a high or low ring is mostly a matter of taste. Keep in mind though that a high ring will visually create a larger gap between 2 straps, and the strap might be more prone to twisting inside the ring.

common styles

Rectangular rings can be made from various materials, including metal (such as iron, brass, stainless steel, or zinc alloy), plastic, and even wood. The choice of material depends on the bag’s style, intended use, and design preferences.

How to apply

Rectangular rings can be sewn directly onto the bag's fabric or webbing, or they can be attached with additional hardware such as rivets or chicago screws.
