A great enclosure starts with better design and materials.
After Hurricane Charley, CRA identified a serious issue with the high failure rate of traditional beams commonly used in screen pool and patio enclosures. Through design evaluation and independent laboratory testing, CRA developed a stronger beam profile that addressed key weaknesses found in conventional beam designs.
After several years of refinement and the development of 9 U.S. patents, the ChannelLock SMB is helping transform the aluminum enclosure industry.
The unique design of the ChannelLock SMB allows it to perform differently than traditional beams, delivering superior strength ratings. This increased strength allows for longer spans, helping CRA produce stronger, more attractive enclosures with fewer fasteners and less material obstructing the view.


Hurricane damage to a Non-CRA pool enclosure illustrates why common materials are prone to failure under heavy loads. CRA uses an exclusive patented beam technology for a beam up to 40% stronger while able to span further distances than traditional beams used in most other screened enclosures.

Florida Product Approval is a designation given to materials certified by the Florida Department of Business and Professional Regulation. It means that ALL material is independently tested and certified by an independent testing facility, and validated annually by an independent third-party quality assurance entity for conformance to testing, alloy composition, hardness, paint adhesion, and paint thickness. In fact this the only beam currently approved with the Florida Product Approval seal.
