[ About Seiko Rack model selection ]
Please see the table.
Please check three points: the material and structure of the truck's tailgate, the tailgate height, and the tailgate length.
Select the item that matches your conditions from the left column (1) to (7) regarding the gate material, structure, and gate height.
Select the spring that intersects with the "Model (combination)" in the table based on the tilt length.

Example : 4t standard body (without crane), installation conditions: normal hinge, tilt step amount 0mm, floor frame height 100mm
○Tilt material and structure: Aluminum Tilt ○Tilt height: 800mm
○Tilt length: L=6.2M

Due to the installation conditions, the main unit is SRC (48781).
Select item (5) based on the gate material, structure, and gate height. The gate length is roughly 6.4 to 8.5 m, so select the SRC550 spring.
(If the tilt length is at the boundary, it is safer to choose a stronger spring.)

*If a steel lashing rail is installed, the unit weight per meter will increase by 3 kg. In the above example, select item (6) based on the unit weight. Given the length of the flap, we recommend selecting SRC550 + auxiliary spring.
