Corrugated Drum

DBCI's industry-leading patent-pending corrugated drum is available for both the light-duty and heavy-duty roll-up doors in standard applications. The corrugated drum improves alignment, enabling the doors to roll-up quicker and tighter with superior control.

Features Include:

  • Smoother cycle operation
  • Sound control
  • Full coverage of the axle and barrel on light-duty roll-up doors


Saddle Clamps

DBCI's single-piece saddle clamp is bolted to the structural bracket for added strength and stability.

Features Include:

  • Quick and easy to install
  • Safe and easy tension adjustments when compared to two-piece alternatives


Tension Set Brackets

Greatly improve the time and effort needed to adjust smaller roll-up doors with DBCI's tension set brackets. Older doors lack tension adjusters and require a technician to re-adjust spring tension. 

Features Include:

  • Faster, facility maintenance personnel can adjust the doors themselves in as little as five minutes using an Allen wrench
  • Safer
  • Easier



The spacer features durable single-piece, aluminum-forged construction and only requires three bolts to install.

Features Include:

  • Easy installation
  • Corrosion resistance



Guides are installed on each side of the roll-up door to allow the door to roll up and down in a smooth transition. The depth of the guides can vary based on the size of the door. A stronger guide allows the door to handle more frequent and demanding operations.

Features Include:

  • Roll formed galvanized steel; size and gauge thickness vary by door model
