This profile has an extra box to the rear increasing the strength of the profile, allowing a stronger fix with less screws. Suitable for internal and external applications. Uses both JN (internal, non re-enforced) and JR (external, re-enforced) Jonc.
Pros - 22mm deep, can be bent / curved around a surface.
Cons - requires a fixing at 250mm centres max, single use.
Note* all Crystal tensioning profiles require a solid fix for the graphic to reach optimum tension. Failure to get a solid fix can have detrimental effects on the graphics tension.
