Harmar Pinnacle SL300: The Ultimate Straight Stairlift for Comfort and Efficiency

Sleek Design and Seamless Integration: Optimized for Straight Stairs

Precision Engineering: Tailored for Straight Staircases

The Harmar Pinnacle SL300 is designed specifically for straight staircases, featuring a durable aluminum rail customizable to your staircase length (up to 32 feet/9.75 m). Positioned only 4.5 inches (11.4 cm) from the wall, it maximizes stair width, fitting staircases as narrow as 29 inches (73.7 cm)—outshining competitors like the Bruno Elan (30 inches/76 cm).

Case Study: In a cozy ranch-style home in Austin, TX, the SL300 was installed on a 9-foot straight staircase. Its slim rail and compact footprint preserved the open feel of the narrow hallway, proving its adaptability in tight spaces.

Compact Folding Mechanism: Space-Saving Innovation

• Folded Dimensions: When parked, the SL300 folds to an industry-leading 11 inches (27.9 cm) from the wall—seat up, arms in, footrest raised—surpassing the Bruno Elan (12.5 inches/31.8 cm) and Handicare 1100 (15 inches/38 cm). This keeps staircases fully accessible for others.
• Unfolded Footprint: Extends to 22 inches (55.9 cm) during use, offering ample room without cluttering the stairs.
• Practical Clearance: Requires just a 10”x10” (25.4 x 25.4 cm) landing at both ends, perfect for homes with limited space or doorways nearby.

Robust Construction and Longevity: Built to Endure

Weight Capacity and Structural Integrity

• Capacity: Supports up to 300 pounds (136 kg), matching the Bruno Elan while handling steeper inclines with confidence.
• Materials:
  • Rail: Lightweight, corrosion-resistant aluminum ensures durability for daily use.
  • Chassis: Steel construction with a powder-coated finish pairs with a cushioned vinyl seat (standard beige, with fabric upgrades available) for comfort and strength.

Reliable Drive System: Quiet and Maintenance-Free

The SL300’s helical worm gear drive delivers a whisper-quiet 40 dBA ride—quieter than the Acorn 130 (50 dBA)—and a smooth 19 feet per minute (5.8 m/min) speed. Rated for over 12,000 trips (10-15 years), its self-lubricating design eliminates the need for grease, reducing upkeep compared to rack-and-pinion systems.

• Torque: Effortlessly manages inclines up to 45°, covering typical residential straight stairs (30°-40°).

Stress-Tested Durability

With rust-resistant components, the SL300 thrives in humid or dry conditions, ensuring consistent performance in basements, garages, or heated interiors.

Power Efficiency and Reliability: Always Ready

Battery Performance: Outage-Proof Reliability

• Power Source: Dual 12V, 7Ah batteries (24V DC) offer up to 40 trips (20 up/down cycles) during outages, matching the Bruno Elan and exceeding the Acorn 130 (20 trips).
• Charging: Recharges in 3-4 hours via a 110-240 VAC outlet, with a smart trickle-charge system and LED indicators (green for full, amber for charging).
• Cold Weather Performance: Operates down to 0°F (-18°C), with an optional package extending to -15°F (-26°C), ideal for unheated areas.

Energy Efficiency

• Standby Draw: Uses just 0.4 amps (about 3.5 kWh/year), keeping costs minimal.
• Active Use: Peaks at 1.8 amps, light on your electrical system.

Diagnostics: User-Friendly Monitoring

LED indicators (green for normal, amber for battery, red for service) and a simple ON/OFF reset keep operation straightforward.

Seamless Accessibility and Safety: Comfort Meets Security

Ride Quality: Smooth and Stable

Traveling at 19 fpm (5.8 m/min), the SL300 uses soft start/stop technology for a gentle, jolt-free experience, perfect for users with mobility challenges. It handles inclines from 30° to 45° with ease.

Seat Comfort: Ergonomic Design

• Dimensions: 19”W x 16”D x 18”H (48.3 x 40.6 x 45.7 cm), wider than the Bruno Elan (17.5”W), with optional padding for added comfort.
• Swivel: Manual 90° swivel at the top (powered option available) ensures safe, easy exits.

Safety Suite: Comprehensive Protection

• Obstruction Sensors: Footrest and chassis sensors halt the lift in 0.4 seconds with an alert if blocked.
• Seatbelt: Adjustable, retractable belt (22-42 inches/56-106 cm) secures users.
• Emergency Stop: Red button on the armrest stops motion instantly.
• Key Lock: Optional lock prevents unauthorized use.

Footrest: Sturdy and Accommodating

• Measures 12”W x 11”D (30.5 x 27.9 cm), supports 100 lbs (45 kg), and folds to 3.5 inches (8.9 cm), fitting larger footwear comfortably.

Installation and Operational Ease: Hassle-Free Setup

Setup Process: Fast and Flexible

The SL300’s rail mounts directly to treads with 5/16” bolts in 4-5 hours for a standard 10-foot staircase, requiring no wall alterations. It fits stairs as narrow as 29 inches (73.7 cm) with a 7-inch (18 cm) tread depth.

Controls: Intuitive and Accessible

• Joystick: Light-touch toggle (0.1 lbs force) on the armrest for easy control.
• Remotes: Two wireless call/send remotes (40-ft/12 m range) for convenience.
• Indicators: LED lights (green, amber, red) signal status clearly.

Portability: Move-Ready Design

Disassembles in 4-5 hours for relocation, making it a future-proof investment for straight stairs.

Aesthetic Integration: Enhancing Your Home

Design Choices

• Upholstery: Standard beige vinyl fits most decors, with gray or tan fabric options.
• Rail Finish: Satin aluminum complements any staircase material.

Visual Harmony

In a Denver bungalow, the SL300’s 11-inch folded profile and neutral tones blended seamlessly with hardwood stairs, maintaining an uncluttered look.

The Critical Role of the SL300’s Design: Solving Real Needs

• Space and Safety: Its 11-inch folded width excels in narrow or busy homes, ensuring accessibility for all.
• Engineering Edge: The helical worm gear offers a quieter, cleaner ride with less maintenance.
• User Focus: A wider seat and robust battery backup cater to diverse needs reliably.
