Series 2 commercial roller doors span up to 5.5 meters wide in one motorized section, ideal for large shopfronts and industrial openings requiring maximum security coverage.
No bottom tracks are needed. The design uses reinforced side guides with brush seals for secure closure while keeping floors clear and accessible for customers and staff.
Solid extruded aluminum slats form the curtain, creating a secure deterrent barrier suitable for retail, hospitality, and high-traffic commercial environments.
Unlimited spans are possible using center mullions to join multiple sections, allowing coverage of any opening size while maintaining structural integrity and smooth operation.
Manual operation uses counterbalance helical springs for smaller spans, while motorized tubular electric motors inside the axle are recommended for wide and high openings.
