Clear House Trainer V4 Chastity Device - 5 Sizes

House of Denial
| /

If you love the classic sliding lock HT V4 design you’re going to really love our clear House Trainer V4 chastity device. We’ve created this fantastic device with improvements over the previous model that we offered.

So what’s changed? There are no seam lines on the rings, so each ring is super smooth on the inside, which makes them significantly more comfortable to wear for long term use.. The parts are all made of higher quality epoxy resin, which is super strong and won’t flex. No more cheating by heating the parts up to flex and release yourself from them.

We really like the new V5 locking system, but we completely understand if you prefer the tried and tested sliding lock. Seeing the classic key design hanging from a chain around your keyholder's neck always makes a slave's cock twitch, which plays a huge role in our tease and denial foreplay.

Unlike the V5 kits our V4 package includes all 4 ring sizes, so they’re great for beginners who want to experiment and don’t know their back ring size. You get the 36mm, 40mm, 45mm and 50mm rings, which are conveniently labelled with the size on the inside.

When choosing your cage size please use the total cage length measurement to make your final choice. The cage size measurement is only the front part of the cage, so using the total length will give you the total tube length. If you’d like to buy an additional cage in a different size at any time please get in touch with us and we’ll help to sort that for you.

It’s taken us some time to have these new and improved kits made and we hope all of our hard work has paid off. Our goal is always to offer the best, highest quality chastity cages that we can for affordable prices and this clear V4 device really is the best you can get for the price.

I feel I must say I’ve given a bit of an unfair review as I used baby oil as lube as I run out of water based. I could pull out with the baby oil as it stays greasy. I must point out with water based lube YOU CAN NOT GET OUT of this contraption. So there you have it , the key holder is your only hope unless you fancy taking work shop tools to it.
