Screw-lock Biothane locking waist belt

Whether you want to keep someone out of their pants or keep something in their pants, our locking waist belts are a fantastic low-profile way to add some extra security to your restraint setup. Made using the same technology as our popular cuffs and collars, our belts are customisable to your heart’s desire and among the most comfortable option out there. Designed for regular wear and made of genuine 25mm or 38mm Biothane® strapping, solid ABS clasps and low-profile security screw lock. These screws aren’t ones you’ll usually find bits for in your standard security screw bit case, so we’ll send you a tool for putting on and taking off your belt. Each belt also comes with a set of points for attaching another lock, for example a padlock or a numbered security seal.

Our belts are fully waterproof and suitable for everyday wear.

What is Biothane®?

Biothane® is a substitute to leather, commonly used in high-end horse-riding accessories and dog harnesses. It’s extremely strong, tough and durable against the elements, and unlike leather does not soak and degrade in water after a long time. It’s available in dozens of colours, from dark leather-like browns to vibrant neons, so we’ll probably have a shade you like the look of.

Getting your measurements

To measure for your belt, you’ll need a simple tape measure. We take measurements in centimetres (cm). Measure around your waist where you would usually wear a belt for your trousers/pants, pulling to a comfortable tightness. We will make your belt to this measurement within a few millimetres, adding a little extra to fit perfectly into our locking mechanism. Due to the complexity of individual preferences on tightness, we recommend you experiment with what feels best before giving us a number. You can provide your measurement after your order if you prefer!

If you would like a locking crotch strap, you’ll need a waist belt to wear and your tape measure. To measure the length of your crotch strap, wear your normal belt in the same place you’d like to wear your locking belt, and carefully measure the length between your belt at the centre of your back, through your legs and up to the locking buckle on your belt. If you’re planning to lock anything substantial under your locking belt, consider wearing it while you measure. For flexibility, we recommend getting an adjustable belt if you’d like a locking crotch strap, but we’ll happily make it fixed if you prefer!

Full measurement information for our restraints

D-rings

By default, our belts are a simple, interlocking clasp and an unbroken Biothane® band, resulting in a beautiful clean aesthetic. For an easy way to further restrain the wearer in the blink of an eye, we also offer all our belt options with a D-ring at the clasps, a welded 304 stainless steel piece that is 20mm across and 3mm thick, extremely resistant to corrosion and hard-wearing. If you fancy a more chunky option for your ring, we offer several other formats, including 4.5mm thick black, rainbow and golden finished zinc. These are also very tough, but they will show their age more quickly with very heavy use.

Taking care of your belt

Our belts are waterproof and will not rust or tarnish in freshwater or saltwater. We use Biothane® and brass eyelets for the main band, and ABS plastic for the locking clasps, that are vapour smoothed to make them more comfortable, easy to clean and glossy. If your belt gets dirty, you can clean it with any body-safe soap and water, and you can safely wear them it the bath or shower. Please take care when wearing clothes that are locked on while swimming and practice safe kink. Biothane® is highly resistant against UV damage, but if you’re storing it for a long time, please put them somewhere out of direct sunlight.

Both parts of our belts are damaged by certain solvents, particularly acetone, used in nail polish remover. If you do spill exotic substances on it, just wash it off with water.

We use brass threaded inserts to catch the screws, and brass eyelets on the Biothane® band, which may slightly tarnish after a long time in saltwater or chlorine-treated water, so if you’re spending days at sea or at the pool, just have a shower afterwards. Our screws and standard D-rings are made from 304 alloy stainless steel, and are impervious to basically everything your skin will touch.

These belts are designed for everyday comfort, to be a reminder of your place and to be a statement piece. You can effectively use them as restraints, but they’re not suitable for extreme weight-bearing such as suspension. Please experiment with your belt before fucking it up. Our clasps are designed to break at the clasp under extreme stress for safety, and the Biothane® band will not usually be damaged.

Picking your band colour

The colour options listed here on this page show the colours as advertised by our main supplier.We now offer both standard colours and a selection of colours retro-reflective bands across the length! Think safety jacket reflective stripes. We know some of you really like these.

If you would like to see how a certain colour looks in particular lighting etc, please get in touch! Certain colours also fluoresce (appear to glow brightly) under deep blue and ultraviolet (UV/blacklight) light, including all neon options, and a few others. If you’d like to know whether a certain colour is fluorescent, get in touch!

Custom colours

We can provide our belts in any colour we can get our hands on. For our main bands, we offer dozens of colours, and if you find another colour you like more that’s available in 25mm or 38mm Biothane® BETA, we’ll source it for you if we can. We make our locking clasps from printed ABS plastic that’s then surface treated. We’ll happily manufacture your clasps in any colours we can source, and can also optionally apply body-safe finishes such as ceramic coatings and paints/clear-coats. If you would like surface finishes added to your belt, please contact us before ordering as we’ll have some material science to do in the paint shop.

Adding text or icons to your belt

If you’d like to add an extra touch of personalisation to your belt we’ll happily apply vinyl lettering or symbols just for you! Whatever your heart desires, if we can apply it (and it’s not too intricate as to where it wouldn’t be strong enough), we’ll do our best to make it happen. We can provide vinyl in dozens of colours, including solid tones, pastels, gloss and matte, reflective, holographic, glittered and plenty more. If you’d like to add an extra touch of you to your restraints, add our vinyl printing to your order. It’s surprisingly cheap!

If you want something customised beyond the options we offer here, please get in touch!
