single hung, tilt, spiral balance wood window parts

A quick learner from Toronto, CA says:
Back in 1997 we did a renovation which included all new windows....

they are ALL wood frame and sash... single (lower) hung & tilt mechanism

So, here are the following main issues I have....

First main issue is the PLASTIC tubing around the spiral balances have dried up, cracked, disintegrated. (see pics)

Second issue.. the manufacturer stupidly designed the pivot bar to be located into the bottom stile, near the kerf for the bubble seal
AND drilled into the END GRAIN of the wood... and the screw holding it in place is located far from the edge
SO !! when you tilt or pull out the sash the pivot bar bends and also cracks the end grain wood (see pics)

1. Do I have to replace the spiral balances?
If yes, yours are aluminum tubing... can I use your diecast metal TILT LATCH with that?

2. Solution for the pivot bar?

I can give you any information you require... dimensions etc...

We do carry the Series 600 spiral balance, which has a 5/8" diameter metal tube. If you want a die cast metal top tilt latch, see our 26-188W, though I don't know how well its measurements match what you have now. For the tilt bar situation, do you think you can retrofit the 26-395 corner pivot bar?

Hi Paul,

My current tilt latch has the same dimensions as your 26-120.

But, I would prefer BLACK and diecast metal.

My concern was is there a lot of FRICTION/WEAR between the diecast
tilt latch and the aluminum metal tube of the spiral balance?

Especially when you're moving it up and down.

We do have one in black metal, our 26-188, but the dimensions are not the same as the 26-120. We do not have anything that matches the 26-120 in black diecast metal, I'm afraid. Take a look and see if you can adapt the 26-188 to your window.

If the tilt latch is constantly rubbing against the spiral balance, I suppose that could present an issue, but if your balance has a metal tube then I think you'll be okay.
