Product review (4 stars): I should have measured or dry fit it first
I applied this seal, removing the paper backing strip as I went, then found out it was 1 1/4"-1 1/2" too short for my Whirlpool-made Kenmore dryer.  I used hot air (from a heat embossing gun, though a hair dryer would work too) to soften the adhesive and very carefully pull it up.  I reapplied the seal, this time stretching gently--this appeared to work fine, but it's annoying that the seal wasn't cut long enough for the repair.
