Class Code 5108
Door Installation – Overhead Doors
Class Code 5108 applies to work installing, servicing, and repairing overhead doors — including residential garage doors, commercial sectional doors, and industrial roll-up doors. The WCIRB pure premium rate for California effective September 1, 2026 is $7.766 per $100 of payroll, a key factor in your workers' comp pricing. Accurate classification matters because overhead door work carries distinct spring, crush, lifting, and electrical hazards that drive claims and safety requirements.
What Class Code 5108 Covers
This classification covers on-site installation, adjustment, maintenance, and repair of overhead doors and their hardware: sectional panels, roll-up/coil doors, tracks, rollers, springs (torsion and extension), cables, drums, and electric openers. Work includes removing and disposing of old doors, fitting and aligning tracks, mounting door sections, tensioning springs, wiring and testing openers and safety sensors, and commissioning loading-dock doors. Tasks performed from ladders, lifts, scaffolds, or service trucks are included when directly related to overhead door work. Routine preventive maintenance and emergency service calls for overhead doors also fall under 5108. Work that is primarily manufacturing, retail sales, or general contracting is typically classified elsewhere.
Who It Applies To
- Residential and commercial overhead door installation contractors
- Service and repair technicians for garage and roll-up doors
- Loading-dock and warehouse door installers and maintainers
- Mechanical installers who tension torsion springs and cables
- Companies that perform on-site overhead door replacement and testing
Common Job Duties
- Assembling and installing sectional and roll-up door sections and frames
- Mounting and aligning tracks, rollers, hinges, and weather seals
- Installing, tensioning, and adjusting torsion and extension springs and cables
- Mounting and wiring electric openers, safety sensors, and control switches
- Using hoists, chain falls, or lifts to raise heavy door sections into place
- Testing door balance, limit switches, reversal systems, and overall operation
Common Injury Risks
Understanding the $7.766 Rate
The WCIRB pure premium rate of $7.766 per $100 of payroll is the base cost to cover expected claims for this class. To estimate pure premium, divide total payroll by 100 and multiply by 7.766 (for example, $100,000 payroll yields $7,766 pure premium). Your final premium will then be adjusted by your insurer's expense loads, experience modification (loss history), payroll reporting accuracy, policy features, and any group or PEO pricing arrangements.
Cal/OSHA Compliance Requirements
Employers must follow Cal/OSHA requirements relevant to overhead door work, including ladder and scaffold safety, fall protection where exposures exist, electrical safety and qualified-person rules for wiring powered openers, and hazardous energy control (lockout/tagout) during repairs. Maintain a written Injury and Illness Prevention Program (IIPP), provide task-specific training (spring handling, use of winding bars, hoist/crane operation), and inspect lifting and tensioning equipment regularly. Documentation of training and competent-person inspections is critical in an audit or after an incident.
How Key HR Helps Employers Under Class Code 5108
A PEO like Key HR helps employers in this classification by centralizing payroll and correct class assignment, administering workers' comp claims to control indemnity and medical costs, and implementing targeted safety programs and training for high-risk tasks like torsion spring handling. Key HR can also support return-to-work plans, preferred provider networks, and data-driven risk management strategies that reduce claim frequency and improve experience modification over time.
Get a QuoteFrequently Asked Questions
Will my garage door installers be assigned to Class Code 5108?
If your employees install, adjust, service, or repair overhead doors (sectional, roll-up, or commercial dock doors) on customers' sites, they are typically classified under 5108. Exceptions include employees who primarily manufacture doors, work in retail sales, or perform general contracting duties; those operations use different codes.
What task causes the most severe injuries and how can we prevent them?
Torsion spring failures and improper spring winding cause some of the most severe injuries. Prevent with trained, qualified personnel, use of proper winding bars and spring containment methods, mechanical lifting aids for heavy sections, two-person lifts, and strict lockout/tagout and electrical isolation when servicing openers.
How can I lower my workers' comp costs for overhead door crews?
Focus on documented safety training (spring handling, ladder use, electrical safety), routine equipment inspections, pre-shift toolbox talks, a formal IIPP, early-return-to-work modified duty, accurate payroll reporting, and proactive claims management. Working with a PEO like Key HR provides centralized claims handling, safety coaching, and purchasing leverage to reduce both frequency and severity of claims.
