Notes: [SADDLE STANDARD DWG(pdf)]
　1. All dimensions are in inches unless noted otherwise
　2. All saddles in this size range must be fully designed. The dimensions shown are a starting place or to be used for estimating only!
　3. Assume that anchor bolts diameter is d - 0.125, where d is the diameter of the hole. Assume that slots for sliding saddle are 6 d long.
　4. N = Number of ribs
　5. n = Number of anchor bolts
