Questions about my internal latch

The Series 600 does look close, but you will have to measure the diameter of the tube to be sure. If it's 5/8" or 9/16", then that's a good choice. The screw plug resembles our 26-200, see if that will work for you.

As for the internal latches, yours is not available. These can be tricky to replace even in the best of time, so you may want to consider replacing your inside tilt latch with a surface mounted tilt latch. This could be a much easier solution in the long run. Watch the video below to see how.
