※The design differs from the SBL-A in that there are balance adjustment screws added at the trailing surface,making for added convenience in precision
    adjustment .Balance adjustment screw holes can be fitted with screw-in plugs(option),eliminating high frequency noise and subsequent vibration.
※The data is not as good as it is available. Please contact CHENA for the remaining dimensions.
