R40 SECTIONAL GARAGE DOORS

R40 sectional garage doors have been carefully designed for simple and easy installation. R40 Sectional garage doors are ideally suited both for new-build houses, and for replacing existing garage doors in traditional properties. R40 sectional garage doors are often referred to as ‘up and over style’, and feature tracks that come fully pre-assembled with tension springs, cables and all the required accessories.

Tension spring assembly - Side-mounted, or under–track mounted springs are factory pre-installed for easy home installation and safe operation. A four spring system ensures that even in the event of one spring failing, the door won’t fall.
A safe and highly reliable track system - All Cable pulleys are covered to protect from injury.
Rubber weather seals ensure the door is properly closed, from the bottom to the top.
The bottom seal works as a shock-absorber, eliminating minor floor imperfections for snug closure.
Finger protection - Anti-pinch panels prevent injury when operating the door.
A convenient internal handle is located at the bottom corner, so the door can be operated even in the event of a power failure.
Many R40 Sectional doors are electrically operated, and for those that feature manual operation, we supply lock and handle kits.
R40 Sectional doors can be supplied with additional upgrades such as a ventilation grill, pet flaps, or an integrated Mailbox.
