Our slat wall hooks are 5/8 long on the  piece that slides behind slat wall.  This is great way to show off your patch hats. 

Note from LSA:
We love supporting other small businesses and this item is shipping from another maker. Because these items are not shipping from our warehouse, they are NOT eligible for our "Free Shipping" thresholds and may have a separate shipping cost associated with them. Turnaround time may vary from what we disclose as our own TAT on the homepage & banner of the website. Custom engraved or printed goods coming from a maker will also have their own turnaround time and the "Rush Shipping" upgrade will not apply.
