Wrist and ankle cuff fit
Compare usable ranges instead of overall strap length.
Find the buckle range
Use the range of usable buckle settings for comparison. An overall strap length can include an area that is outside the fastened circumference.
Confirm each piece in a kit
Wrist cuffs, ankle cuffs, and collars have separate measurements. Check each relevant range instead of relying on a single fit label for the entire set.
