## Description

PB Locking casement fastener

Review: Quality - Competitive pricing and quality
Review: Transformed my old windows looks brilliant - I recently installed the Modern Locking Window Fastener JW78LPC on my older windows, and I am absolutely thrilled with the results! My windows were perfectly functional, but the old fasteners were looking tired and didn't offer the modern security I was after. I wasn't ready to replace the entire windows, so I was looking for a solution that would "smart them up" without breaking the bank. The JW78LPC fasteners have done exactly that. They were surprisingly easy to install, and the transformation is remarkable. My windows now look incredibly smart and modern, as if they've had a complete overhaul. The polished chrome finish is sleek and adds a touch of contemporary elegance that complements my home perfectly. Beyond the aesthetics, the locking mechanism feels incredibly robust and secure. I now have complete peace of mind knowing my windows are properly secured. It's amazing how such a relatively small upgrade can make such a huge difference to both the appearance and security of your home. If you're looking to refresh and "smart up" your existing windows without the cost and hassle of full replacement, I cannot recommend the Modern Locking Window Fastener JW78LPC enough. They look brilliant and have genuinely transformed the look and feel of my home.

## Questions & Answers

**Q: Will this work for a 29 year old casement window. I would attach a photo of the existing one but there doesn't appear to be any option to attach it.**
A: I am by no means a window expert(!) but I've just used it on a 25 yr old wooden casement window to replace the broken one that was there. I just used some wood filler for the old holes as this was a different size between the screws to the existing. Not sure about if it's a pvc window though

**Q: How do these fit to both sides? Looks like its for right-hand only?**
A: No it fits either way as you can move th handle 180 degrees I.e lock it in an up or down position

**Q: In the photo I looks like one handle and two bottom pieces, is this the case? Or is it just 1 handle and 1 bottom fixing?  Thanks in advance**
A: When delivered it came with a handle and 2 bottom fixings but we didn’t need to use the 2nd bottom Fixing.

**Q: is it available in brass**
A: It was and in black too
