CLIP REFERENCE
H = Hard Clip
S = Soft Clip
E = Spring Clip
P = Pad under Rail
Example:- 24S/A100
24 = BOLT DIAMETER
S = SOFT CLIP
A100 = RAIL SECTION
Example:- 20EP/BS113A
20 = BOLT DIAMETER
E = SPRING CLIP
P = PAD UNDER RAIL
BS113A = RAIL SECTION

NOTE: Pad Thickness - SP Clip

The leg length and bolt/stud length is based on a resilient pad thickness of 5mm, however other pad thicknesses can be used and adjustment will be made to bolt/stud length and leg length.
