Costs can add up quickly when you have 1000 plus stores.  Even the small items like peg hooks.  After scrubbing our store prototype for cost reductions we realized we would have two different style of peg hooks.  One style for the existing grid merchandising system, and the new proposal for a more economical merchandising bar system.  Realizing this would cause havoc in the field when doing projects and having two styles of pegs to manage was unacceptable.  After some thought and research I devised a new peg hook that incorporated both of the pegs attachment points and didn't compromise stability.
