The rungs have a flat surface on their top edge and a beveled surface on their bottom edge. The board also has at least one slot formed through the board with such slot being formed in the uppermost groove and also formed in various other groups for purpose of height installation. The slots are used in conjunction with a support strap having a permanent stop formed on one end and the other end has a loop end such that a removable stop can be inserted into the strap loop end once it has been inserted through the back of the slot on the finger board such that it advances through the front of the finger board.
