Instant purchase without comments is OK! Rod holder base wood, base block Angle: Normal, Height: Upper wood approx. 45mm, Lower wood approx. 35mm Non-slip material on the back for stable fixation. Also, many other rod holder base woods are on sale! Square timber not included. Square timber dimensions: approx. 9cm x approx. 5.3cm Made of sen wood (fine wood), so it is very durable and sturdy. It will not be excessively dented by the pressure of the clamp, and it will not corrode due to seawater, so it can be used for a long time. This is a base wood that tilts the rod holder towards the sea surface. By tilting it, the bouncing of the rod tip is reduced. It is convenient for fishing with a rod placed on a stand, like veteran anglers who tilt their rods when fishing for Bishi Aji or Komase Sea Bream. Please set it on the boat edge as shown in the image. Be sure to set the lower support wood. Without the support wood, it will become unstable and the rod holder may come off. The angle can be raised horizontally with the rod holder bolt. Made to fit perfectly with Daiwa Light Holder 90CH and Daiichi Seiko Mini Lark. Please refer to the images and measure the clamp size to see if it fits your rod holder before purchasing. Returns and exchanges are not accepted. Please contact us within 48 hours.
