I have a 40 year old threshold that is partially covered by tile cement and I am having a difficult time in finding a replacement vinyl insert. The old insert looks like the 58-168 but the measurement is 1 3/8" wide. I want to avoid the 1 1/2" or larger size as part of the door bottom is putting excess pressure on the old insert. I don't know the threshold brand.

You are the ONLY source that I know of that stocks a replacement threshold insert for our 44-year-old thresholds in a 136-unit condominium complex. Installation tip given by an expert: Lubricate with soapy water, insert the inside edge of each side first, then the outside edge of each "T". Using an awl or icepick or even a nail, press in the outside fin and slide the tool down the threshold. The insert goes in smoothly and quickly!
