CB-X The Curve Clear Chastity Cage Kit

CB-X The Curve Clear Chastity Cage Kit for Larger 3¾-Inch Fit in Canada

The CB-X The Curve Clear Chastity Cage Kit is the largest CB-X male chastity cage system, designed around a longer 3¾-inch cage and a wider 1½-inch inner diameter. Five included U-ring sizes, multiple locking pins and four spacer lengths allow the base fit and cage spacing to be adjusted instead of relying on one fixed configuration. Made from lightweight medical-grade polycarbonate plastic, the transparent cage is vented with functional openings for urination and easier cleaning. Available in Canada at Discreet Life, The Curve is the CB-X option for users whose measurements require more internal length and width than the brand's smaller cage models.

Largest CB-X Cage with a 3¾-Inch Length

The Curve sits at the largest end of the CB-X chastity cage range. Its 3¾-inch cage length provides more internal length than the CB-3000, CB-6000, CB-6000S and Mr. Stubb models, making accurate measurement especially important when deciding whether The Curve is the right CB-X configuration for you.

Wider 1½-Inch Inner Diameter

Length is not the only difference. The Curve also provides a 1½-inch inner diameter, giving it more internal width than other common CB-X models. This combination of added length and width is the primary reason to choose The Curve rather than simply moving to another finish of a smaller CB-X cage.

Five U-Rings for Customizable Base Sizing

The complete kit includes five standard CB-X U-rings so you can work through different base-ring sizes when establishing your fit. Included sizes are #1 at 2 inches, #2 at 1⅞ inches, #3 at 1¾ inches, #4 at 1⅝ inches and #5 at 1½ inches.

Four Spacer Lengths for Additional Adjustment

Multiple locking pins work with corresponding spacers to change the distance between the base assembly and cage. The supplied spacer lengths are 11.8 mm, 15.1 mm, 18.2 mm and 21.4 mm, allowing another level of adjustment beyond the U-ring itself.

Clear Polycarbonate for Easier Visual Inspection

The transparent finish makes it easier to visually inspect the positioning, fit and cleanliness of the cage while retaining the rigid CB-X structure. The medical-grade polycarbonate is lightweight, while ventilation and functional openings provide access for routine hygiene.

Complete Kit with Two Locking Options

The Curve is sold here as a complete chastity cage kit, not simply the individual cage. In addition to the fitting components, the package includes a reusable brass padlock with two keys and five individually numbered single-use plastic locks, giving you two different locking approaches from the start.

Pairs Well With

The complete Curve kit already includes the five standard CB-X U-ring sizes and several locking options. If the largest included 2-inch ring is still too small, the separately available XL U-ring extends the sizing range, while replacement numbered locks are useful once the five included single-use locks have been used.

How to Use

• Measure the penis while fully flaccid before selecting The Curve.
• Confirm that the 3¾-inch cage length and 1½-inch inner diameter suit the intended fit.
• Select the U-ring that feels secure without excessively restricting the base.
• Choose a compatible locking pin and spacer combination for the desired cage spacing.
• Apply compatible lubricant during fitting as needed.
• Assemble and secure the cage according to the CB-X instructions.
• Keep an appropriate removal method readily accessible.
• Clean and completely dry the reusable components between uses.

Responsible Use

Correct sizing is especially important with chastity devices. The cage should feel secure without causing significant pain, numbness, swelling, unusual discoloration, coldness or other signs of restricted circulation. Remove the device promptly if concerning symptoms occur. Do not force an anatomy size into a cage simply because The Curve is CB-X's largest model, and follow the manufacturer's fitting and care instructions when increasing wear time.
