Sewing protective cover

Purpose: Sewing protective covers can be used to protect screw rods, light bars, columns, spindles, and other circular rotating columns.
This type of shield can be used horizontally or vertically. When using horizontally, it is recommended to use plastic or aluminum support rings to maintain a certain uniform distance between the inner cavity of the shield and the screw rod, in order to extend the service life.
When the stretching length is large, metal rings can be added at each compromise to improve the stability of the shield. Metal flanges are usually used for connecting or fixing ends, but sleeve type can also be chosen.
