Features & Benefits
Professional Series Heavy-Duty Engineering
The LOMAX Professional Series was developed for truck owners who place greater demands on their equipment. While maintaining the sleek appearance and convenience of the standard LOMAX platform, the Professional Series incorporates additional extruded aluminum reinforcement channels beneath each panel.
This enhanced structural design provides:
- Increased panel rigidity
- Improved durability
- Enhanced load distribution
- Greater long-term strength
- Commercial-grade performance
Despite its reinforced construction, the Professional Series remains lightweight enough for easy everyday operation and removal.
For professionals who use their trucks as mobile workstations, this additional strength helps ensure years of dependable service.
Rugged Urethane Diamond Plate Finish
One of the defining features of the Professional Series is its aggressive Urethane Diamond Plate finish.
Inspired by industrial diamond plate materials commonly found in commercial and heavy-duty applications, this finish delivers both durability and distinctive styling.
Benefits include:
- Anti-skid textured surface
- Durable alloy construction
- Corrosion resistance
- Scratch resistance
- Impact absorption
- UV protection
Unlike traditional polished diamond plate surfaces that can be difficult to maintain, the urethane-coated finish retains its appearance while offering outstanding resistance to environmental wear.
The result is a truck bed cover that looks as tough as it performs.
Low-Profile Design with Premium Appearance
The Professional Series maintains the signature low-profile styling that has made LOMAX one of the most popular names in hard folding tonneau covers.
The cover sits close to the truck bed rails, creating:
- A streamlined appearance
- OEM-inspired styling
- Reduced visual bulk
- Enhanced vehicle aesthetics
- Seamless integration with factory bed caps
The sleek profile complements both work trucks and show-quality builds alike.
Automatic Dual Locking System
Security is a major priority for truck owners, and the Professional Series is equipped with an automatic dual-locking system that combines convenience with confidence.
Both locking points can be released simultaneously by pulling the integrated release cord from either side of the truck bed.
Heavy-duty reinforced nylon latches provide:
- Positive lock engagement
- Smooth operation
- Reliable long-term performance
- Enhanced cargo security
This system allows quick access to the truck bed while maintaining dependable protection when the cover is closed.
Automatic Ten-Point Locking Security
Every panel of the Professional Series automatically locks into place as it is unfolded.
The reinforced locking system secures the cover at ten separate points, providing:
- Enhanced theft deterrence
- Improved panel stability
- Uniform security across the entire cover
- Automatic engagement without manual locking
This advanced locking design helps protect valuable cargo while simplifying everyday operation.
Advanced Weather-Tight Protection
Protecting cargo from the elements is one of the most important functions of a hard tonneau cover.
The Professional Series incorporates multiple layers of weather protection, including:
- Waterproof hinges
- Continuous side rail seals
- Flexible rubber weather stripping
- Water-shedding panel design
- Bed rail overlap protection
Unlike some truck bed covers that rely on gutters or drain tubes, the LOMAX Professional Series naturally routes water away from the bed while helping prevent moisture intrusion.
This makes it an ideal vehicle storage solution for:
- Tools
- Electronics
- Camping equipment
- Hunting gear
- Luggage
- Emergency supplies
Strong Yet Lightweight Construction
The Professional Series offers an exceptional balance of strength and usability.
Its reinforced aluminum framework supports up to 400 pounds of evenly distributed weight while maintaining an overall cover weight of approximately 40–50 pounds
Benefits include:
- Excellent strength-to-weight ratio
- Easy one-person operation
- Improved durability
- Simplified removal and reinstallation
- Long-term structural integrity
This combination of strength and convenience is one of the reasons LOMAX covers remain highly regarded among truck owners.
Integrated Storage Clips
When hauling oversized cargo, the Professional Series folds forward and secures using integrated retractable storage clips.
Features include:
- Secure folded-panel retention
- No adjustments required
- Reduced movement during transport
- Improved panel protection
Rubber-padded standoffs maintain proper panel spacing while minimizing vibration and wear.
TIGHT BITE Clamp Installation System
The Professional Series installs using LOMAX's proven TIGHT BITE clamp system.
These specially engineered clamps feature precision-cut teeth that provide:
- Exceptional gripping strength
- Secure installation
- Damage-free mounting
- Long-term reliability
The system eliminates the need to drill into the truck bed while providing outstanding holding power.
Simple Removal & Reinstallation
When maximum bed access is required, the Professional Series can be removed quickly by a single person.
Removal process:
- Fold the cover completely open.
- Secure the integrated storage clips.
- Pull the front panel latches.
- Slide the cover rearward to disengage mounting hooks.
- Lift the cover from the vehicle.
Reinstallation is equally simple. Slide the cover forward, engage the hooks, and lower it into the retainment brackets where it automatically locks into place.
This flexibility makes the cover ideal for truck owners who frequently haul oversized cargo.
Quiet Ride Design
The Professional Series is engineered to minimize vibration and unwanted noise during travel.
Features include:
- Flexible rubber seals
- Limited metal-on-metal contact
