Isetshenziselwa ngokukhethekile ukulungisa inkinobho ye-D-ring namabhande akhethekile ezicathulweni zokuqwala izintaba, izicathulo zokuzivocavoca nezicathulo zomshwalense wabasebenzi, njll.
Isici:
1. Umshini onama-servo motors, ukuvikelwa kwemvelo kuthule kakhulu, ukusebenza okuzinzile.
2.Ukuphakela okuzenzakalelayo yomibili ingxenye ye-D-ring enewasha ephansi.
3. Ama-opharetha akusadingeki ukuthi abeke amahhuku mathupha ngaphambi kokuwalungisa.
4. Ukuphakela okuzenzakalelayo kanye ne-riveting yakho kokubili ingxenye ye-D-ring enewasha ephansi iqinisekisa ukuphepha nokusebenza kahle okuphezulu.
