The bottom of the door has to be cut to the correct height and angle to seat properly on the rubber strip. **Q: How much is the space between the screw holes?** A: I drilled my own holes so unsure what the original ones measured at. **Q: Can the hall carpet tuck underneath this for neat finish?** A: Yes but we do recommend applying some adhesive sealant to both the channels, whereas if that was applied on the inside channel, the sealant would just be sticking to the carpet and depending on the thickness, the carpet may raise the threshold at one side. Also, please note that the bottom of the door needs to be cut at a slight angle for this threshold, so the door needs to be removed. There are fitting instructions in the link below: https://www.stormguard.co.uk/stormguard-products/cdx/ If it is not possible to remove the door, then you may want to look at the SG100, which is a very similar threshold, but you can fit with the door in place with no need to cut it. https://www.stormguard.co.uk/stormguard-products/sg100/ **Q: can i use on upvc door?** A: You have to screw it to the floor,and the floor has to be flat. On most UPVC doors the bottom of the doorway has a lip and is not flat. If you only have a UPVC door and the doorway is wooden then you should be able to fasten it to the floor. ## Frequently Bought Together - STORMGUARD 04SR0050914A Aluminium CDX Compression Threshold Door Sill - Stormguard 07SR5640914A 914 mm XRD Rain Deflector with Rubber Seal - Aluminium - STORMGUARD 03SR0210838A 838 mm BDS Rubber Bottom of The Door Seal-Aluminium, 838mm / 33inches Long --- ## 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/50194989-cdx-compression-threshold-door-sill-aluminium](https://www.desertcart.co.za/products/50194989-cdx-compression-threshold-door-sill-aluminium) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-27*
