45-4590 is a 45mm x 90mm metric 45 series rectangular T-slot profile with six open T-slots, two on each 90mm face and one on each 45mm face. The profile is smooth, which makes it resistant to dirt and debris buildup while also being easy to clean. The 45-4590 profile is compatible with 45 series fasteners. This profile lends itself to work spaces, machine guards, and displays. The six open T-slots enable access from any direction and are useful for mounting accessories.
