AArrow Fire , Stratford TF50B: door seal

Featured Replies

Just on the off chance, does anyone know what the diameter of the fire rope for the Fire Door is?

 

I have the manual, (it doesn't say what the diameter is) I have rung the supplier; the lass had no idea what the diameter is.

So, as usual, I end up on BH asking everyone else. Phhh....

 

 

Aye, and I totally misread the OP. Thinking about FD30s...

They offer 8, 10, and 12mm rope.

The spares list I have doesn't specify the diameter. The person who fields sales calls doesn't know the correct dimensions  (they used to employ a lady who knew the product range inside out and backwards). Getting the diameter  correct means the difference between over-firing, and not.

 

So I'll order some of each and experiment.
