Rolling Steel Door Bottom Seal – 1.50" 150-Series Vinyl Bulb – Black

150' Black

• Category: Rolling Steel Door Seal

• Rolling Steel Door Vinyl Bottom Seal 150 – Black (Commercial Bottom Weather Seal)

  This is a commercial rolling steel door bottom seal system, typically used on coiling/roll-up steel doors where the bottom bar uses a dual-angle retainer that clamps the seal in place. The “150” in your URL commonly refers to the 1.50" (1-1/2") profile size, which matches standard rolling steel bottom seal geometry.

  What this seal does in the system

  The bottom seal is the primary ground-contact sealing point on a rolling steel door. When the door closes:

  • The rigid portion locks into the bottom retainer (usually aluminum angles)
  • The flexible bulb compresses against the floor
  • It blocks:
    • Air infiltration
    • Dust & debris
    • Water intrusion
    • Rodents and insects

  It works together with:

  • Side guide seals
  • Header seal (HS-22S / HS-625 type systems)
  • Hood baffle seals

  So in system terms, this is the final compression seal that completes the building envelope at the floor line.

  System-Level Role (Important)

  Think of this part as the “compression interface” between building and floor:

  • If it’s worn → you lose sealing even if side seals are perfect
  • If it’s undersized → drafts and water intrusion happen
  • If it’s oversized → door drag, motor strain, and premature wear

  In real-world performance, this seal directly affects:

  • Energy efficiency of the building
  • Pest control in storage units
  • Water intrusion at ground level
  • Door closing smoothness and load on operators
