A flat front plate can be wider than its base ring: locate the assembly's true widest point, compare front and side views, and use the width in clothing decisions.
This guide is not medical advice. Stop use if significant pain, numbness, swelling, discoloration or circulation concerns occur.
Flat cages exist to reduce profile, and their plates sometimes succeed so well sideways that the plate — not the ring — becomes the widest part of the assembly. That inversion changes the clothing math: the ring measurement you optimized no longer describes the outline your trousers meet.
This guide locates the widest point, reads both views, separates plate from ring measurements, and applies the width where it lives. The plate-shape background is in the front-plate comparison; the category context in the flat-cage guide.
Locate the widest part of the assembly
Assemble the complete device — plate, ring, lock — and find the widest span. On some flat designs the plate’s diameter exceeds the ring’s outer width; on others the ring’s wings or hinge dominate. The widest point is the number your clothing meets, whichever component owns it. Measure the assembly laid flat, photograph it with the ruler in frame, and record the location of the maximum beside the value.
The record format matters: “assembly widest at plate, 62 mm, ring outer 50 mm” tells the whole story that “62 mm” never will.
Compare front and side views
Width is a front-view fact, but depth is a side-view fact, and flat designs trade between them. Compare both: the front view for how much side-to-side span the plate claims, the side view for how far the plate and lock project forward. A plate that is wide but shallow reads slimmer under fabric than a narrow-but-deep assembly of the same measurements — the two views together are the real outline.
Photograph both views with the ruler and keep them with the widest-point record. Your clothing decisions deserve both dimensions, not the flattering one.
Check plate and ring measurements separately
Record plate width and ring outer width as two rows, not one blended “width.” The separation pays twice: when comparing candidates (a wider plate on a narrower ring can still read slimmer than a narrow plate on a bulky ring, depending on the side depth), and when ordering replacements (plate and ring are different parts with different specifications). Blend them and both uses break.
The Flat Gatling’s circular plate and the Butterfly Flat’s sculpted wings demonstrate the separation: similar profiles, different width distributions, both measurable only if you kept the rows apart.
The Flat Gatling Chastity Cage
The plate-dominant example: The Flat Gatling’s circular perforated plate is the design where plate width can exceed the ring’s outer span — measure the plate’s widest point as the assembly’s true maximum. Check: its package list is not fully enumerated in the readable listing; confirm the complete included set and ring options with the seller before ordering the width test.
Use the width in the clothing decision
Apply the widest-point number where it lives: trouser selection, underwear panels, the seated outline check. A cage whose assembly is widest at the plate pairs best with structured front panels and stretch fabrics that pass over the span; a cage widest at the ring behaves like any ring-anchored device and follows the standard under-clothes guidance. The width number is an input to your wardrobe, not a verdict on the cage.
Re-check after any hardware change — a different ring or lock moves the widest point, and the clothing decision follows the new maximum.
Butterfly Flat Chastity Cage
And the sculpted alternative: The Butterfly Flat distributes its width into wings at a stated 133 g — its widest point typically sits at the wing span with the lock valley below it, a different outline than any circular plate of the same central mass. Check: photograph front and side with the ruler; the wing shape’s widest row belongs in the record beside the ring’s.
Find the true widest point, keep plate and ring rows separate, read front and side, and give the number to your wardrobe instead of your worries. Flat cages manage profile for a living — measuring the assembly’s real maximum is how you let them do their job under yours.
