  – No layout necessary
  – No cutting necessary
• Order Bolt-On RRL® with a new pulley and Douglas will install
  it free of labor charge
• Reduce conveyor downtime and pulley installation/removal cost
• Ideally suited for severe applications
• Heavy steel backing plate with rolled in crown and truck tire tough 1/2" SBR/Natural rubber revitalizes old pulleys and adds years of service life
• Improve traction capacity of any pulley with Douglas Bolt-On RRL®
• Easy-on easy-off principle means that Douglas RRL® may be installed in the field without removing the pulley or the conveyor belt
• Minimum gap between segments means unequaled belt to pulley contact and more traction

Construction

• All standard lagging is hot vulcanized in our plant to strict tolerances and the highest industry standards
• Diamond groove standard

Options

• Optional Herringbone/Chevron groove or plain wrap cloth impression available
• Available in the same range of materials as Douglas conveyor pulley lagging

Installation

1. Follow all OSHA, state and owner safety procedures. Lock-out, tag-out all equipment before servicing, never, never operate, adjust or install equipment on a moving conveyor.
2. Clean pulley face of dirt and buildup.
3. Place first rim segment on pulley. Hold in place with welder’s clamps each end.
4. It may be necessary to pull the middle down with chain. Be sure each segment fits snug against face (prevents segment flexing and weld fatigue).
5. Drill holes in pulley rim using holes in segments as template.
6. Bolt segments to pulley face.
