Lockd Cobra Range Explained: Which Model Fits Your Goals
The Lockd Cobra range includes six cages, ranging from 1.35 inches to 4.33 inches: Baby, Nub, Nano, Small, Standard, and Maxi. Each is made from body-safe resin, comes with four ring sizes, and is available in black, pink, and transparent. This guide breaks down what separates each model so you can match length, fit, and level of restriction to your own goals.
What Is the Cobra Range?
Lockd built the Cobra Chastity Cage Collection to solve a problem most single-model chastity brands run into: no one cage fits every goal. Someone chasing extreme discretion has different priorities than someone building toward long-term comfort, and a beginner needs something more forgiving than someone with years of experience.
Instead of one-size-fits-all, Cobra splits into six lengths, from the 1.35-inch Baby to the 4.33-inch Maxi. Every model shares the same foundation: body-safe resin construction, a flared base ring for a secure fit, an integrated lock, and four interchangeable ring sizes (38mm, 43mm, 48mm, and 52mm) so you can dial in fit without buying a separate kit. All six are available in black, pink, and transparent.
| Model | Length | Best for |
|---|---|---|
| Baby | 1.35" | Maximum discretion, 24/7 wear |
| Nub | 2.2" | Advanced, long-term restriction |
| Nano | 2.6" | Intermediate — airflow + restriction |
| Small | 3.5" | Dependable everyday long-term wear |
| Standard | 3.7" | Beginners — roomy and forgiving |
| Maxi | 4.33" | Tease-and-denial, room to grow |
Cobra Baby
At just 1.35 inches, the Lockd Cobra Baby is the shortest cage in the range and is built for maximum discretion. Its low-profile shape sits close to the body and stays virtually undetectable under clothing, making it a common choice for 24/7 wear.
Best for: Submissives who want the most discreet possible fit, couples committed to a full-time dynamic, or anyone transitioning from a standard cage down to something smaller.

The Cobra Nub measures 2.2 inches and is built for advanced, long-term restriction. It keeps the same vented, flared-ring design as the rest of the range, so airflow and hygiene aren't sacrificed for the shorter length.
Best for: Experienced users pushing further into denial play, and partners looking for a higher-security option without moving to a rigid steel cage.
View the Cobra Nub →Cobra Nano
At 2.6 inches, Lockd's Cobra Nano is built around a breathable mesh structure that prioritizes airflow alongside a compact, restrictive fit. It's positioned as a step up from the shortest cages for wearers who want more room while keeping things secure.
Best for: Intermediate wearers advancing from a shorter cage, or anyone who wants a strong balance of restriction and daily comfort.
View the Cobra Nano →Cobra Small
The Cobra Small from Lockd comes in at 3.5 inches, a mid-length option built as a dependable everyday cage for structured, longer-term wear. It's designed as a middle ground for wearers who've outgrown beginner cages but aren't ready for the roomier end of the range.
Best for: Wearers transitioning from a beginner-friendly cage into a more secure, long-term option, and D/s dynamics built around consistent daily wear.
View the Cobra Small →Cobra Standard
At 3.7 inches, the Standard is the second-longest cage in the lineup and the one Lockd recommends most often for beginners. It's built to be roomier and more forgiving while still enforcing a strict form of denial.
Best for: Beginner to intermediate wearers who want a lightweight, comfortable cage suitable for long stretches, and keyholders easing a partner into daily wear.
View the Cobra Standard →Cobra Maxi
The Cobra Maxi is the longest cage in the range at 4.33 inches, with an elongated design that provides more room to grow inside. That structure makes it a popular pick for tease-and-denial play, since arousal becomes part of the experience rather than something the cage eliminates entirely.
Best for: Wearers who want extra length and a breathable fit, and keyholders who enjoy prolonged teasing as part of the dynamic.

A few questions to work through before picking a length:
- How experienced are you? The Standard is Lockd's most recommended starting point; the Baby and Nub suit wearers with more experience under stricter restrictions.
- Is discretion the priority, or long-term comfort? Lockd's Baby and Nub sit closest to the body for discretion, while the Nano, Small, and Maxi trade a little length for breathability and daily comfort.
- Do you want room to grow inside the cage, or maximum restriction? The Maxi is built for the former, and the Baby and Nub for the latter.
- What's the dynamic? Solo wearers and keyholder-led dynamics can both work with any model, but stricter cages tend to suit established dynamics where teasing and control are already part of the routine.
Whichever length you land on, ring size matters more than the cage itself for day-to-day comfort. Our ring size guide walks through finding the right fit before you commit to a model.
