Our microrails have extruded screw holes in order for customer to be able to assemble slide rail from one side (except for full extension types: 2000S, 1400S, 1600S).
If long screws were to be used, it would interfere with retainer or slide rail stopper, and it may cause damage.
Please make sure the length of screw before use.
Recommended length of screw could be determined as following calculation.
Recommended length of screw (L) = (t) + (A) + (1～1.5) mm
