Border Calculation Formula

    border Neck Tianhua left a roar Wind throat Neck height
    20mm B-28mm B-20mm B-25mm 50mm
    25mm B-40mm B-30mm B-35mm 50mm
    32mm B-52mm B-40mm B-45mm 50mm
    • B = Base Size (Meter)
    • Assuming a 25mm edge is chosen, the face value is 300mm.
    • Neck gauge = 260mm
    • Ceiling height = 270mm
    • Air vent hole = 265mm

Other borders/methods

    • A frame thickness of less than 20mm is not recommended.
    • Narrower bezels will have less impact on appearance and rigidity, thus reducing the risk of installation distortion.
    • Narrower frames require more precise ceiling openings.

Frequently Asked Questions

    • Can the neck be thinned?
    • No, the neck depth of double-leafed plants must be at least 50mm. If it is less than 50mm, consider using single-leafed plants (ASE), which only need to be 25~32mm.
