Why this score
Can you find out what you are buying before you sign? Published pricing is weighted hardest because it is the rarest and least game-able signal in this category.

ANSI/SMA 6001, AS5039 and AAMA 1901 all count equally here — each is a recognised third-party protocol. We do not rank the standards against each other, because they measure different things and no neutral crosswalk exists.
- Third-party standard: AS503918 / 18

- Publishes numeric test results — Knife shear, dynamic impact, jemmy and pull testing; impact figures up to 369 ft-lbs cited third-party3 / 3
What the maker is still on the hook for after the install. A long warranty that covers labor and transfers with the house is worth more than a headline number on parts only.
- 10-year warranty9.3 / 14
- Warranty does not state both labor cover and transferability0 / 6
- No break-in guarantee0 / 10
How the mesh is held in the frame is the usual failure point under lever attack. Naming the mechanism is a competence signal; refusing to describe it is not.

Stated editorial position, not a performance metric: we weight US manufacturing because it shortens warranty recourse and supply lead times. Readers who do not share that preference should subtract these 10 points — the breakdown below makes that easy.

Where it's strong
- Patented Screw Clamp retention with concealed tamper-resistant screws — a named, specific mechanism at the exact point where cheaper screens fail.
- AS5039 testing covers knife shear, dynamic impact, jemmy and pull; it is the most demanding published protocol in the category.
- The longest track record of any system sold in the US, with roughly 107 North American dealers.
What to watch
- Publishes almost nothing verifiable: no prices, no wire diameter, no alloy grade, no frame material, no warranty terms on its product pages.
- Everything routes through a dealer consultation, which makes comparison shopping slow and opaque.
- Dealer coverage is thin outside the Sun Belt, and install quality varies by dealer.
Crimsafe: common questions
Why does Crimsafe score below Boss here if the engineering is respected?
Because it declines to publish. Crimsafe's screw-clamp retention earns full marks in that group and its AS5039 testing scores nearly full marks. It loses on disclosure — no prices, no wire gauge, no alloy, no published warranty terms — and on the guarantee and domestic-manufacturing groups. A spec you cannot check is a spec you cannot rely on, and that is a deliberate position of this rating.
What is Screw Clamp and does it matter?
It clamps the mesh mechanically into the frame instead of holding it with a rubber spline. It matters a great deal: spline-held mesh is the usual failure point under sustained lever pressure. It is the single strongest item in Crimsafe's favour.
