Photo is a side view of metal threshold.
Need to replace Zeluck (out of business) exterior mahogany door proprietary design threshold weather strip. The proprietary design includes a lip over the bubble but could probably seal well enough without the lip! Have 2-1/2" sample to submit.
Bubble is 6/16ths" wide, 'tee' is 3/16th's wide. Stem distance between tee flat strip and bubble is 1/16th".
Adding a photo of the existing (Zeluck proprietary) weatherstripping profile to show the 'lip' above the bubble. Don't think the lip is critical.
