The Preston Venta-Lite Hooded Side Tray is built with extra strong knuckles, allowing it to be used without any additional support. This is a benefit for anglers looking to keep both costs and the weight of their luggage load down. However, if you are storing large quantities of bait, it is recommended that a side tray support arm is used for complete peace of mind. The tray comes supplied with square inserts at 23mm and 25mm, and round inserts at 30mm. It also features a convenient measure on the front of the tray, giving you an easy way to create accurate hooklengths or track the depth you are fishing at.
