## Description

Do you have aluminum framed, vertical or horizontal sliding windows with loose-fitting, worn or missing locks? Besides adding a “new look” to your windows with a fresh set of locking hardware, these sash locks can help add peace of mind by restoring the security features on your sliding windows. These locks feature a design that allows them to lock aluminum-framed single-hungs, double-hungs and horizontal sliding windows without the need of a keeper. Each lock features a cam-type locking mechanism that mounts on the checkrail of the innermost sash and engages into the checkrail of the outermost sash. The upper, outermost sash on vertical sliding windows determines if it is a “single hung” or “double hung.” If the upper, outermost sash is non-movable, then it is a single hung window. A “double hung” window refers to both sash having the ability to slide up and down for ventilation purposes, and these sash locks can fit on both model types, in addition to some left/right horizontal sliding windows. The locks are constructed of diecast zinc and come in a corrosion-resistant, industry standard, white-painted finish to match other existing hardware that may already be in the home or office. Depending on the size of the sash, these locks can be used as singles or in pairs. Each set includes one lock, installation fasteners and simple instructions. Installation of these locks is quick and easy and can be done with a simple handheld Phillips head screwdriver. Other design features include a 3/8 inch latch projection, cam-action fastening, and 2-1/4 inch mounting hole centers. Compare the style and dimensions of this lock to those required on your sliding windows and order yours today.

## Questions & Answers

**Q: How many come in a pack/order?**
A: One which includes both pieces.

**Q: My cam is 1/2`` long, from bottom of base to bottom of cam. Is this cam flush with bottom of base of unit? Photo looks like it?**
A: Hello D.
Yes it should be possible. The lever inside from the middle I measured is 0.75” so when you turn it out you still have a 3/8” notch.
Best regards

**Q: This works for slide left to open windows.  Is there one for slide right to open windows?**
A: I bought these window locks awhile ago.  They were used to replace locks on my travel trailer slide windows.  These locks worked on both left and right sliding windows by inverting them and they worked fine.  The old latches were a different style and harder to operate.

**Q: Can I change the orientation of the handle for the window sliding to the right?  This one looks like for the left sliding window.**
A: No, the orientation of the handle cannot be changed.
