I messed with that for awhile. Push w22 "in" first, then push straight "down". The downward travel is about 3/8 of an inch.
The down force needed is quite a bit
I'll give it a try... felt like I was already usin' quite a bit of force but I'll go "lean on them a bit"
The W150 & W22 wall frames are the same design concept, but "algin slots" are different and the size is a wee bit different.
Sidenote: This is going to be addicting, less than 24 hrs up and running with the Axioms and I just ordered a W100 for Dual Centers, above and below display.
Thanks
