1530-S is a 1.50" x 3.00" fractional 15 series rectangular T-slot profile with six open T-slots, two on each 3.00" face and one on each 1.50" face. The profile is smooth, which makes it resistant to dirt and debris buildup while also being easy to clean. The 1530-S profile is compatible with 15 series fasteners. The center cavity of the profile can be pressurized up to 150 psi, lending itself to work spaces, machine guards or displays.
