Our Mini Review

Athmer seals are cycle tested to 1,000,000+ cycles. They simply won't fail. We constantly hear reviews of other drop seals that only last several months before the spring mechanism fails. Not with Athmer seals -- simply the best seal on the planet.

Need a quite office space? HIPPA privacy space? Odor containing space-- keep it in. Private doctor office? Any space requiring privacy, draft protection, air/odor isolation can be enhanced by an Athmer drop door seal.

Installation Instructional Video

Some competitors offer up to 12" of cut back in the field so their standard lengths will fit many different door widths. This high cut back length simply leads to weak spring strength towards the lock side. Athmer has fine-tuned their standard lengths to ensure a reasonable cut back length while ensuring equal spring strength across the entire length of the drop seal. No spring failures and a perfect seal.

Loose the threshold! NO MORE TRIPPING HAZARDS!

With Athmer drop seals, tripping hazards on door thresholds are a thing of the past. All athmer sealing systems are barrier-free - with no ifs or butts. Our zero threshold solutions for doors even fall below the requirements of the German Industrial Standard (DIN 18040). This standard tolerates threshold heights of up to two centimetres, even for barrier-free construction.
