Your cart is empty.Part # STL020* *STL017 was integrated into this design and has been superceded by STL020 GREAT NEWS! There are several external cooler block configurations from several manufacturers, BUT the universal fit design features of the new STL020 accommodate most all 2 line in and 2 line out style blocks. The STL020 supersedes the STL017 and since it works with in-line and offset blocks, NOW ONE KIT upgrades more blocks. Universal fit eliminates confusion. Block variations are fully explained with cutaway views to make it simple!
