What it does

Positioning control puts you in command of your anal play. Adjust the angle from shallow teasing to deep penetration, customize insertion depth to match your comfort level, and fine-tune the pressure against your prostate. Stainless steel construction maintains whatever position you set, giving you consistent control over intensity and targeting throughout your session.

Setup and operation are straightforward with the VAC-U-Lock system. Snap any compatible attachment onto the base in seconds—no threading, twisting, or complicated assembly required. Your positioning control works seamlessly with the easy attachment system: set your preferred angle, lock in your chosen sex toy, and maintain that perfect setup throughout extended play. If you're looking at alternatives, Sybian Sex Machines offer motorised options for hands-free automated stimulation.

Specifications

  • Shaft length: 16 inches, adjustable
  • Material: Premium grade stainless steel
  • Attachment system: Universal VAC-U-Lock compatibility
  • Base: Non-slip design to prevent movement during use
  • Cleaning: Non-porous surface, soap and water

Fit and sizing

The 16-inch steel shaft gives you a long reach with adjustable depth control, so you're not locked into one insertion length. Start by positioning yourself comfortably and adjusting the angle to target your sweet spot—this is where customization matters more than raw size. Cockringshop specialise in products for men and couples, and sizing here is about what feels right for your body and comfort level, not about impressing anyone. If you're new to anal play, the positioning adjustability lets you start gentle and progress at your own pace. The non-slip base keeps everything stable, so you can focus on sensation rather than balance.

How to use it

Select your preferred attachment and snap it onto the VAC-U-Lock base—the connection is instant and secure. Position yourself comfortably and adjust the angle to target your sweet spot. Moisture helps significantly: add lubricant to both sides for smooth entry and comfortable movement. Stainless steel warms to body temperature quickly, so give it a moment before you begin.

Fine-tune the depth and angle as you go, taking advantage of the positioning control to find what works best for your prostate. Your attachment stays locked in place until you're ready to switch, making it easy to experiment with different textures and shapes during the same session without interrupting your rhythm. Cleanup is straightforward—rinse the non-porous steel surface with soap and warm water when you're done.

Feature breakdown

Feature Specification Benefit Experience
Adjustable Positioning 360-degree angle control Precise prostate targeting Customize to your anatomy
VAC-U-Lock System Instant attachment mechanism Versatile stimulation options Effortless sex toy switching
Steel Construction 16-inch stainless steel Firm, consistent pressure Reliable positioning hold
Non-Slip Base Weighted design Stability during use Hands-free positioning control

Who it suits

Perfect for experienced users who want precise control over their anal play and beginners who appreciate straightforward operation. Solo players love having both hands free to focus on other sensations while the adjustable positioning maintains perfect prostate contact. Couples benefit from the quick setup that keeps spontaneous moments flowing smoothly without fumbling with complicated equipment.

Skip this if you prefer a fully motorised hands-off experience—you're manually adjusting the angle and depth here, which is the whole point for some people but not for others. If you want vibration built in, a motorised sex machine is a different category. This one rewards active engagement and gives you control over every variable.

Tested and quality-checked

Every new line we stock is inspected by hand before it goes live — we check the build, the finish, and the materials, and we confirm it is safe and fit for how it will be used. Nothing is used for its intended purpose; it is examined, checked, and re-boxed. What that means for you is simple: you receive a piece we have already vetted, not a guess off a supplier's pallet. See how we test every product →

How it compares

Stainless steel is rigid with no give, which means it holds your chosen angle firmly and delivers consistent, unvarying pressure throughout your session. That's different from silicone or rubber, which flex and compress slightly under pressure. Attachments For Sex Machines come in various materials, so you can swap between rigid steel and softer options depending on what you want that day. Steel also warms to body temperature, while softer materials stay cooler longer. Choose steel if you want firm, predictable pressure; choose silicone or rubber if you prefer some give and flex.

Please read — safety first. Put the ring on before you are fully erect and use plenty of water-based lubricant so it slides on without pinching. Keep wear time short — no more than 20 minutes while you are getting used to it, and never fall asleep wearing one. Take it off straight away if you feel numbness, coldness, a change in colour, or any pain, as these mean blood flow has been cut off too far. Never share between partners without cleaning the item first or using a fresh condom. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle.

What you can use it with

Pair this with other Anal Sex Toys designed for the VAC-U-Lock system to swap between different shapes, sizes, and textures mid-session. The quick-change mechanism means you can experiment with butt plugs, prostate toys, and other compatible attachments without stopping or breaking your rhythm. Having multiple compatible sex toys on hand lets you find exactly what hits right for your body.
