extruded latch lock

Hello!

Thank you for reaching out to us. Yes, the 90-182 is made of extruded aluminum. I hope this information is helpful.

These types of spring-loaded latch locks slide into the end of the window lift rail at the bottom of the sash. They are slid in at the end of the lift rail and in some cases, the channel that the lock slides into is "pinned". As a result, the lock will not slide out of the channel. You might need to remove the sash from the window to slide the locks out of the lift channel. If the lift channel has been "pinned", you'll need a small flat-blade screwdriver to open up the channel.
