Tilt window shoe from West Window double-hung

Marked 530CSB, Patent number 5704165. Measures 1 & 7/32nd" (1.2188) wide X 2 & 3/16th" (2.1875) tall X 1/2" (.50) thick. Metal curved "comb" at the top & door on back enclosing blue pivot button which, when rotated from its normal horizontal position, expands shoe, perhaps to stop shoe from sliding up or down track when removing sash. Many many thanks, Bob

I ordered the 15-046 that you suggested and the 15-015, which is a 32nd thicker. Mainly because the blue "button" is much closer to mine(the "guide" at the top of the pivot bar slot is thin, closer to 1/16th than the represented 3/32nd of the 15-046. No measurement of that "guide" in the 15-015 spec, might be that it just looks thinner because it blue. Anyway, many thanks and I'll let you know how it works out. Bob

my 25yr old West windows pivot shoes are going bad. The photos in this thread are dead accurate. The old plastic shoe needs to be replaced but...

Not finding replacement parts and no reply from West windows, I have come up with a circumvention to the problem.

1. Cut off the bar tee projections (easy) and then grind the bar flat.
2. Procure a 5/8 inch shoe measuring 17/32 X 1 13/16 X 1 9/32. Note the vertical length of the shoe is not critical.
3. If you look at the photos originally posted here, you will see what was the problem: the bar that mated with the shoe had projections on each side making a 'tee'. I have never found a good shoe match for this. If you look at the photo, this particular shoe was made to accept the tee projection with cutouts extending into the shoe body- rare.

Removing the slight projections from the vinyl window bar, that mates into the shoe, makes it fairly easy to remedy the parts problem.
