These sand spike holders are a set that allows you to keep your fishing cart organized and functional for a great day of fishing!!! Once installed they can swivel out for use or swivel in when not in use. They are very easy to install, you can place them on your cart frame wherever you like (I usually measure and place them 24" apart from each other) then drill the 4 holes and install the supplies stainless steel nuts and bolts. For sand spike holders on both sides of your cart you would need 2 sets. The area where sand spikes go measure 7" x 4" and can hold 1-8 sand spikes. All orders are shipped via UPS ground to the LOWER 48 only. This listing is for 1 set of spike holders, fishing cart is not included.
