It relates to top rails used as handrails and various fence caps installed in stadiums, baseball fields, etc., and as guard rails installed in buildings, factories, ships, elevators, automobile roads, etc.

Conventionally, the caps installed on the stairs of buildings and used as handrails are made up of a metal cap holder that is passed between the pillars, and a vinyl hand rail that is placed over the kasagi holder.
A hot air blower is used to cover the Kasagi holder with a vinyl hand rail.

In addition, the guard rails that have been installed in buildings until now are rigid bodies, and when an impact load is applied, their elastic deformation characteristics and cushioning effect as a beam are insufficient. The structure of the installation was complex, the number of parts was large, and the construction was complicated.

The purpose of this invention is to have excellent elastic deformation as a beam when an impact load is applied, in other words, to have an excellent elastic range deflection as a beam, and to have an excellent cushioning effect. Can be used for fences, guard rails, etc.
To provide a top rail which has a simple structure and a reduced number of parts, which simplifies installation work, which also strengthens the installation and can be manufactured robustly and inexpensively.

In response to these challenges, the top rail of this invention consists of a metal hollow core with a slit extending in the length direction.
