Terminology
W.T.--Weights include boxing, subtract 1-2 lbs. for installation weight. Weights may vary 1-2 lbs. due to packaging variations.
I.R.--(Installation Rating) is a rough measure of the time required for baseplate or bracket installation by a skilled mechanic. #1 being the easiest and #5 the most difficult.
GRP--Group numbers refer to relative price categories. "I" being the least expensive and "V" being the most expensive for the Blue Ox baseplates. "A" being the least expensive and "C" being the most expensive for the speedometer disconnects.
Note: Group numbers do not refer to Duncan brackets. (They are all the same price)
RNK--Indicates the popularity of each baseplate or bracket based on sales history. Only the top 75 are ranked.
N--An "N" appearing in the "RNK" column signifies that the baseplate or bracket is new and may be increasing in popularity.
SO--An "SO" appearing in the "RNK" column signifies that the baseplate, bracket or speedometer disconnect is available by special order only. They are subject to obsoletion based on future sales activity. (Call for availability).
