• All models (except #420) include seals which are offered in two materials: soft closed cell sponge neoprene (R) which remains pliable down to -70°F and PemkoPrene® thermo-plastic elastomer (PK).
• Especially over uneven surfaces, both PemkoPrene® (PK) and nylon brush (NB) provide excellent seals to keep out draft, dust, moisture, insects, fumes, light, and sound.
• All models (except #430 and #412) are non-handed and reversible. Installation is fast and easy because disassembly is not required to change handing: simply flip the automatic door bottom and you’ve reversed the hand.
