Frequently Asked Questions
How tall does a St. Andrews cross need to be?
The top attachment points should be at or above wrist height when the person's arms are raised at a 45-degree angle. For most people this means a cross height of 7 to 8 feet. Check the restrained person's height and arm reach before purchasing.
Do you need to bolt a St. Andrews cross to the wall?
Freestanding models with a wide base do not require wall mounting and are stable for most activities. Wall mounting adds stability for high-force impact play. If using a freestanding cross, verify the base footprint is rated for the intended activity level.
What restraints work with a St. Andrews cross?
Most crosses have D-ring attachment points compatible with standard BDSM cuffs. Padded leather or neoprene wrist and ankle cuffs are recommended over rope for extended restraint scenes on a cross, as they distribute pressure more evenly and are faster to remove in an emergency.
