Answer:
The 5000 LRX utilizes a 6-point plastic cradle with a smooth rotary ratchet adjustment mechanism and weighs 378 grams. By contrast, the 5000 L uses a manual plastic slip-fit harness (370 g), while the 5001 L and 5001 LRX variants employ textile suspensions.
The Udyogi Ultra 5000 series covers four distinct suspension and fitment configurations sharing the identical high-density polyethylene (HDPE) shell mold with triple top-rib reinforcement:
- 5000 LRX (This Model): 6-point plastic suspension equipped with a rear rotary wheel ratchet fit mechanism; weight is 378 grams; packed 40 pieces per master carton.
- 5000 L: 6-point plastic suspension equipped with a manual pin-lock slip fit mechanism; weight is 370 grams; packed 50 pieces per master carton.
- 5001 L: 6-point woven textile suspension with manual slip fit adjustment.
- 5001 LRX: 6-point woven textile suspension with rotary ratchet fit adjustment.
The plastic ratchet mechanism on the 5000 LRX allows operators to micro-adjust headband tension between 530 mm and 600 mm using one hand without removing work gloves.
