CB-X U-Ring XL Black Cock Cage Replacement Ring

CB-X U-Ring XL Black Cock Cage Replacement Ring for Larger Fit in Canada

The CB-X U-Ring XL Black Cock Cage Replacement Ring is an extra-large chastity cage U-ring designed for users who need more room than the standard rings supplied with CB-X chastity kits. With a 57.2 mm (2¼-inch) inner diameter, this XL ring is the largest U-Ring size offered by CB-X and is compatible with all CB-X chastity devices. Its lightweight medical-grade polycarbonate construction provides a durable, reusable replacement or sizing option. Available in Canada at Discreet Life, the Black XL U-Ring is ideal for existing CB-X owners who need a larger base-ring fit without replacing their complete cage system.

57.2 mm XL Fit Beyond the Standard CB-X Ring Set

Complete CB-X kits include five standard U-Ring sizes, with the largest standard #1 ring measuring 50.8 mm (2 inches) across the inner diameter. This separately sold XL U-Ring increases that opening to 57.2 mm (2¼ inches), providing another sizing option when the standard rings are too small.

Interchangeable Across CB-X Chastity Devices

CB-X uses a modular component system, so this XL ring is not limited to a single cage model. It can be used with compatible CB-X cage assemblies, making it useful as a replacement for a lost or damaged ring or as an additional sizing option for an existing setup.

Medical-Grade Polycarbonate Construction

The ring is made from lightweight medical-grade polycarbonate plastic. The rigid construction helps maintain the intended shape of the base component while keeping the replacement piece relatively light for regular use.

Black Finish for a Classic CB-X Setup

The Black version provides a clean, understated appearance that coordinates naturally with Black CB-X cage components. The colour changes the appearance only; the XL sizing, material and CB-X compatibility are the same as the Pink and Transparent versions.

Compare CB-X XL U-Ring Colours

All three XL U-Rings provide the same 57.2 mm inner diameter and CB-X compatibility. Choose between Pink, Transparent and Black based on the finish that best matches your existing cage or preferred look.
