ERA 826-33 Sash Window Screw Locks - Brass (6 Pieces)

Really good set of sash window locks. My windows only had the original push bolts but I decided that they were not very secure so looked at unobtrusive but much more secure replacements. These really excelled.Fitting was a doddle and I used the original holes in the sash frames so very little alteration. A couple of the fixing holes needed drilling out a little more but that was it.

Easy to install - soLong as you have sash windows bothnof which open - as it says in description ! Don't even think about it if only One of your windows opensNeat and unobtrusive / would have been 5 stars had they not supplied Just one key meaning you have to buy more if You use six locks In More than one room - Which of Course You would unless You have a Mansion with three windows in the same Room!

Sash windows are not the most secure of things, this purchase will ease those worries. Get packet of 6, open packet, close windows, mark/measure where on the window you'd like these to be screwed in - equidistant from the sides of the window or from the central lock. Drill hole through to the other window so that your two windows have holes where both will meet (being careful not to drill all the way through both). Bang the small bit into the rear window, the large bit into the front window (it doesn't really matter if your hole in the rear one is a bit deeper than the bit you're knocking in, it's just to house the screw once in place. Insert long metal screw and once turned a few times, use key to sink the head just below the level of the front housing. Your window should now be secure and should not move. Two in each window - unless they're massive, should suffice.

These would of been great had they fitted my modern sash windows. As with most 'new' things, material is kept to a minimum, so in my case there was not enough wood to drill and fit these without breaking the frame

Ordered whole set to replace two lost bolts from same brand of locks fitted 20+ years ago into very old cottage (I wasn’t hopeful to find a replacement, but helpfully the brand name is etched onto the original key-super). Fit perfectly into existing barrels and key works for both both old and new bolts; very pleased thank you.

Overall, quite an annoying product. The packaging said to use a 10mm drill bit. I found that to be too small for the rear pane piece (I had to use a 10.5mm bit to get it to stick) but too large for the front pane, because the brass cylinder spins and moves around too easily while rotating the bolt with the key. The bolt obviously also comes free completely once you unscrew it, which means it's lose and knocking around (and easy to lose) if you open the window. Very inconvenient only having one key, too, especially if you use the 6 piece set across multiple rooms. That said, it seems to be well made and serves its purpose of securing the window once in place. It's just not a very elegant solution.

Very nice the only complain I've got is that you have to buy a set of three unfortunately I only have two sash windows I would Have preferred to buy them singly or in pairs

Easy to fix. Needed these after renovating rear sash window above flat roof. Some left over if needed for further sashes.
