Description
xOverview
The CMI RP105 is a compact, high-strength 3-inch single pulley designed for demanding rigging tasks. It combines a lightweight aluminum sheave with durable stainless steel sideplates and a hardened, ground steel axle. With an impressive 16,000 lb MBS, this pulley aims to balance strength and reliability in a compact package that’s easy to handle on crowded rigs.
Key specifications
- MBS: 16,000 lbs
- Rope cap: 5/8" (15.5 mm)
- Side plates: Stainless steel
- Mechanics: Bushing
- Weight: 1.35 lbs (0.61 kg)
- Max diameter: 5/8" / 15.5 mm
Materials and build quality
The RP105 pairs an aluminum sheave with stainless steel sideplates, delivering a notable reduction in weight without sacrificing durability. The axle is hardened and ground, offering smooth operation and long wear life. The bushing-based mechanism supports steady, predictable movement under load, contributing to consistent performance in real-world setups.
Performance and practical uses
This pulley is suited for lift and rigging scenarios where a sturdy, reliable component is needed in a compact form. The 5/8" rope capacity aligns with common rope diameters in field use, while the stainless sideplates resist corrosion in variable environments. The combination of a robust MBS rating and precise, low-friction mechanics makes it a practical choice for temporary rigs, theater rigs, sailing setups, or light industrial applications.
Why choose the RP105
- High load capacity (MBS 16,000 lbs) for demanding tasks
- Low weight at 1.35 lbs enhances portability on site
- Aluminum sheave for efficiency and reduced wear
- Stainless sideplates for corrosion resistance in challenging environments
- Solid, bushings-based mechanics for smooth operation
Care and usage tips
Inspect the pulley for wear and corrosion before use. Clean and lubricate the bushing area as needed to maintain smooth rotation. Ensure the rope diameter stays within the 5/8" capacity for optimal performance.
