The KR-1018 Gunmetal Wrist Cuff Spreader Bar combines two rigid metal wrist restraints with a fixed 34cm connecting bar, creating a substantial restraint design with a distinctive gunmetal grey finish.
Measuring approximately 34cm overall, with 20cm of rigid bar between the cuffs, KR-1018 provides a fixed-width wrist restraint arrangement. Each cuff has an approximate 53mm internal diameter and 69mm external diameter, giving customers useful measurements to check before purchasing.
The metal wrist cuffs are secured using an Allen-key locking mechanism, while a centrally positioned hole in the connecting bar provides an attachment point for a compatible rope or chain.
The fixed 20cm gap between the 53mm cuffs keeps the wrists evenly spaced and stops them twisting together, which suits partners moving on from soft cuffs to a rigid restraint; the central attachment point lets you secure it to a bed or hook, but never take body weight through it.

Why Choose the KR-1018 Gunmetal Wrist Spreader Bar?
KR-1018 provides a distinctive alternative to adjustable strap-based restraints by combining rigid metal construction with two integrated wrist cuffs.
The 34cm overall length and 20cm fixed spacing between the cuffs give the product a clearly defined restraint position, while the 53mm internal cuff diameter provides an important sizing reference before purchase.
The gunmetal grey finish also helps distinguish KR-1018 from polished silver metal restraints, while the central attachment hole provides an additional connection point for a compatible lightweight rope or chain.
Choose this short fixed-width bar for wrist control in front of or behind the body; for ankles or a wider stance, the adjustable spreader bars are the alternative.
How to Fit & Use
Check the 53mm internal cuff diameter before use to ensure an appropriate fit.
Position each wrist carefully inside the cuff before securing the Allen-key locking mechanism. Ensure the restraints are secure without causing excessive pressure or pinching.
If using the central attachment hole, connect only suitable lightweight accessories. Do not use the bar or attachment point for body-weight suspension or excessive loading unless an appropriate manufacturer load rating is provided.
Regularly check circulation, skin colour and sensation during use. Release immediately if there is numbness, swelling, significant discolouration or persistent discomfort.
Always keep the Allen key immediately accessible so the cuffs can be released promptly when required.
Cleaning & Care
Wipe the metal surfaces clean before and after use and dry thoroughly before storage.
Regularly inspect the cuffs, connecting bar, locking mechanisms and central attachment hole for signs of wear, corrosion, rough edges or damage.
Check that both Allen-key fastenings operate smoothly before each use and discontinue use if either restraint cannot be secured or released reliably.
For consenting adults aged 18 and over.
