When I was looking for lock for my workshop 17 mm seemed the most narrow available. Hope this helps. **Q: What is the measurement in between the two bolts - existing one is 7mm between both bolts** A: Measuring from the underside of the latch to the top of the bolt on this particular lock is 12mm, hope that is helpful. **Q: What measurement is 64mm? i need to replace a faulty lock and obviously want to buy the right size. existing lock is era but can't see anything 64mm** A: It's the depth of the lock. i.e the mortice in the door needs to be 64mm or more in depth to house the lock. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality lock *by W***N on 22 February 2026* Very pleased with the heavy duty easy to install and works well with a smooth action. Bought it to replace an old Union lock which was getting worn and notch. ### ⭐⭐⭐⭐⭐ Good lock *by M***Y on 1 March 2026* Fitted perfectly and works. Good quality lock would recommend ### ⭐⭐⭐⭐ Excellent Value. Easy to Fit as a Direct Replacement *by P***R on 7 May 2025* Quality of the keys don't seem as good as a previous purchase of the same make and model. But it was a great price from the Warehouse. The latch bolt was the wrong way around - easy to fix but probably why it had been returned. Very easy to install - 10 minutes including switching the latch bolt around and reinstalling. ## Frequently Bought Together - ERA Fortress BS 3621 2.5-inch/ 64mm 5 Lever Maximum Security Mortice Sashlock - Chrome Effect - Black Antique Door Handles Lever Lock Plain --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/48992336-fortress-bs-3621-2-5-inch-64mm-5-lever-maximum](https://www.desertcart.co.za/products/48992336-fortress-bs-3621-2-5-inch-64mm-5-lever-maximum) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-25*
