A cage’s listed length may describe the usable cage section, the outer body or the entire device. Those measurements are not interchangeable, especially when electronics add bulk. Use the electric chastity collection alongside this dimension checklist, and ask for clarification whenever a product diagram does not identify exactly where the measurement starts and ends.
Name the dimension before comparing numbers
A listed length may refer to the inside usable cage space, the outside cage shell, the full device including its lock, or a manufacturer-defined segment. Diameter may refer to an inner opening or the outer shell. Never subtract two unlabeled numbers to “calculate” internal room. Ask for a marked diagram that shows start point, end point and whether a controller or ring is included.
The sizing guide covers personal measuring. This page decodes product diagrams so the measurement you obtained can be matched to the right product dimension.
Cage space and overall length are different
Pro Cellmate 3 offers regular and long cage profiles and an adjustable snap-ring system. Its electronic display and casing create an external shape that is not the same as the usable space inside. If a listing gives only an overall dimension, do not treat it as internal cage length. Ask for separate internal and external length labels for the selected regular or long option.
Package photos can show the difference in structure but cannot provide a precise scale. Compare only measurements that identify the same endpoints. If the manufacturer cannot supply a dimension you need, keep it marked unknown rather than filling it from an image.
QIUI CAGINK Pro Cellmate 3 App-Controlled Smart Chastity Cage
Pro Cellmate 3 offers regular and long profiles with an adjustable snap-ring system. Ask for labeled internal and overall lengths for the selected profile. See the product details and confirm the selected option before ordering.
Where electronics add to the external profile
MetalShake is a compact aluminum-alloy smart cage with app locking and vibration. Its listed length and diameter describe a product profile, but the electronics and lock can add to the outside shape. Confirm the measurement arrows in the selected model’s current chart. The outer housing may affect clothing clearance while internal opening determines a different fit question; neither can be derived reliably from the other.
Record the base ring separately, including its inner size and attachment. A ring diameter should not be compared with cage diameter as if they measured the same part.
QIUI CAGINK MetalShake App-Controlled Metal Vibrating Chastity Cage
MetalShake adds an integrated electronic housing to its aluminum-alloy cage. Its listed dimensions need labeled endpoints before they can answer internal clearance. See the product details and confirm the selected option before ordering.
Compare fixed and extensible structures
An extensible silicone cage with an optional vibration plug is another structure entirely. “Extensible” describes a design feature, not an unlimited length range. It offers short or long selected cage options, so check the stated dimension and the range documented for the chosen version. Do not assume a plug-equipped package has the same profile as one without the plug.
Even a soft-looking material does not establish internal clearance. Ask for a neutral, non-body diagram with the cage at the manufacturer’s defined measuring state and a separate label for overall length.
A dimension glossary for product charts
Use this request sheet for a seller; leave a number blank when no marked diagram exists.
| Dimension | Measure between | Why it matters |
|---|---|---|
| Internal cage length | Inside base to inside end | Usable space |
| Overall device length | Outermost start to end | External profile |
| Cage opening | Inner edges at stated point | Entry/clearance |
| Ring inner size | Inner ring edges | Separate ring fit |
| Controller/lock projection | Outside housing edges | Added bulk |
Request a precisely annotated, non-body product image and the exact variation name. A lifestyle photo or subtraction from overall length cannot replace these labels.
Extensible Silicone Chastity Cage With Vibration Plug
The extensible silicone cage offers selected short/long and with/without-plug options. Extensible construction is not an unrestricted length specification. See the product details and confirm the selected option before ordering.
A useful chart names each measured part and its endpoints. Keep internal cage, total device, ring and controller dimensions separate until the manufacturer labels them.
