Double Screw Negative Male Chastity Cage With Catheter

The Double Screw Negative Male Chastity Cage With Catheter is a medical-grade stainless steel chastity device engineered for maximum security and extended wear. Its double screw locking mechanism and integrated catheter design deliver complete restraint control. It suits men pursuing long-term 24/7 lockup with precision fit across four ring sizes.

The product itself

The Double Screw Negative Male Chastity Cage With Catheter is built from medical-grade stainless steel with a precision-engineered double screw mechanism that creates an escape-proof seal. Every edge is rounded, every dimension calculated. The cage measures 4.2 cm in length and houses a 3.4 cm catheter insert, with four ball ring sizes spanning 40 mm to 53 mm so you achieve a genuinely custom fit rather than a generic compromise. Unlike simpler single-screw designs, the dual mechanism gives you and your keyholder absolute certainty that removal is impossible without the key—a crucial distinction when planning extended lockup. The polished silver finish resists tarnishing and maintains its lustrous appearance through weeks of continuous wear.

What sets this cage apart is the engineering sophistication. The weight—235 g total—is substantial enough to remind you of your locked status throughout the day without becoming uncomfortable. The smooth stainless steel and thoughtful proportions mean you can wear it continuously for weeks without pressure points or circulation issues. The integrated catheter adds a dimension of control you won't find on basic designs. If you're new to catheter functionality, comparing this integrated approach to standalone urethral dilators shows how the cage's design prioritises security alongside sensation control.

The features that matter

• Double screw mechanism: Superior locking system prevents any escape or unauthorised removal, keeping you or your partner fully in control through extended wear periods.
• Four ring sizes: Choose from 40 mm small through 53 mm extra-large for the perfect anatomical fit that stays secure day and night without circulation loss.
• Integrated catheter: 3.4 cm insert adds control and functionality specifically calibrated for extended wear scenarios and improved restraint dynamics.
• Medical-grade stainless steel: Hypoallergenic, rust-resistant, and easy to clean thoroughly for long-term hygiene and longevity with minimal maintenance.
• Polished silver finish: Elegant aesthetic that resists tarnishing and maintains sharp appearance through regular wear and basic cleaning routines.

The detail

• Dimensions: Cage 4.2 cm length; catheter insert 3.4 cm; ball rings in four sizes: 40 mm, 45 mm, 50 mm, 53 mm.
• Material and weight: Medical-grade stainless steel throughout; total weight 235 g for substantial presence without discomfort.
• Closure: Double screw security mechanism—two separate screws that must both be locked for absolute tamper-proof closure.
• Finish: Polished silver; tarnish-resistant and maintains lustre with basic care and regular cleaning.
• Box contents: Chastity cage with integrated catheter, four precision-fitted ball rings, double screw closure system, and keys.

How to use an urethral toy safely

Before inserting the catheter, wash the cage and your hands thoroughly with warm water and soap. Lubricate the catheter insert generously with a water-based lubricant suitable for urethral play—this reduces friction and prevents tissue trauma. Insert slowly and steadily, never forcing. Stop immediately if you feel sharp pain (discomfort is normal; pain is not). Once the cage is seated, engage both screws fully and test the mechanism to confirm the lock is secure before your keyholder takes the keys. Check daily that the cage sits comfortably without pressure spots on the scrotum or penis.

During extended wear, inspect the cage each time you clean it for any signs of irritation or discolouration. Urethral play requires sterile technique—keep all contact surfaces clean and change the position of the catheter occasionally if you're wearing it for weeks. If you experience pain, swelling, discharge, or difficulty urinating, remove the cage immediately and seek medical advice. For users new to catheter sensation, products like curved penis plugs offer less invasive exploration of urethral play before committing to cage-based catheter wear.

Who should buy it

Care and storage

Wash the cage and all components with warm water and mild soap immediately after wear or at minimum daily during extended lockup. Dry thoroughly with a soft cloth to prevent water spots on the polished finish. The stainless steel resists rust, but regular drying preserves the lustrous appearance. Store in a clean, dry place away from moisture. Do not use harsh chemicals, abrasive scrubbers, or ultrasonic cleaners, as these damage the polished finish. The double screw mechanism requires no special maintenance beyond basic drying.

What to expect

The double screw mechanism is genuinely escape-proof—this is its defining feature and the main reason to choose it over single-screw alternatives. Engagement requires deliberate turning of both screws with the keys; you cannot accidentally jar it loose or partially opens up it through pressure or movement. During the first week of continuous wear, most users report a psychological shift as the weight and immobility become routine rather than novel. The cage's proportions are calculated to contain without crushing, but first-timers often underestimate how constant the sensation is—you feel it most when you think about it, less so during distraction.

The integrated catheter adds sensation and requires adjustment in cleaning routine. After insertion, the catheter sits internally and you will feel urethral pressure continuously. This is normal but intense for first-timers; insertion should be slow and heavily lubricated. Some users find the first 48 hours of catheter wear the most noticeable before sensation normalises. Cleaning is straightforward—warm water and mild soap—but you must maintain consistency to prevent any buildup or irritation around the insertion point.

The four ring sizes mean you should measure your scrotum carefully before ordering. Most users find their ideal fit is snug without pressure; if the ring is too tight, circulation suffers and discomfort increases sharply; if too loose, the cage may shift during movement. Getting the ring size right from the start prevents the need to reorder. The polished stainless steel shows fingerprints and water spots, but these wipe away easily and do not affect function or durability.

Long-term wear (weeks to months) is where this cage's engineering shows. Users report zero degradation in security, no corrosion, no discolouration, and sustained comfort through extended lockup. The substantial weight (235 g) becomes a feature rather than a burden—it provides constant, subtle reminder of your locked status without becoming painful or fatiguing. Couples who use this for power exchange dynamics report that the double screw's irreversibility deepens the psychological impact compared to simpler designs.
