Rubber tape (expander) is designed to perform physical exercises in sports facilities, as well as at home.
Expander is a rubber strip of rectangular cross section.
Depending on the width, the following expanders are manufactured: 1 and 2 types, which must conform to the dimensions given in Table 1:
| Size Name | Number 1 | Number 2 | ||
| nominal | max. deviation | nominal | max. deviation | |
| Length | 2500 | ±50 | 2500 | ±50 |
| Width | 100 | ±10 | 120 | ±10 |
| Thickness | 1,0 | ±0,3 | 1,0 | ±0,3 |
