Towel racks can be divided into:

1. Soft lead single-ended tube: stainless steel soft wire is led out from the heating tube and covered with a glass fiber sleeve.

2. External wiring single head tube: The stainless steel hard wire is led out by the lead rod in the heating tube, and then connected to the high temperature wire outside the high temperature wire. This process is a standard process, and the domestic single-head tube is led out in this form, with low cost and wide application.
