Roll N Lock a Series
The Roll N Lock A Series retractable tonneau cover represents one of the premier truck bed security systems on the automotive aftermarket, blending the rugged durability of an all-aluminum hard cover with the smooth, compact convenience of a retractable roller mechanism. Unlike vinyl roll-up covers that offer minimal theft resistance or heavy fiberglass lids that restrict oversized cargo hauling, the A-Series features powder-coated interlocking aluminum slats that roll smoothly into an ultra-compact canister. Whether you drive a Ford F-150, Chevy Silverado, Ram 1500, or Toyota Tacoma, protecting valuable tools, sports equipment, and camping gear from weather and theft is paramount. In this comprehensive product guide, we analyze the Roll N Lock A Series engineering, weatherproofing capabilities, clamp-on installation steps, and maintenance best practices.
All-Aluminum Slat Architecture, Low-Profile Canister, and Security
The defining feature of the Roll N Lock A Series is its rigid, all-aluminum construction. Unlike its sibling the M-Series—which overlays a vinyl layer on top of aluminum slats—the A-Series features an exposed, textured matte-black powder-coated aluminum surface that delivers a sleek, low-profile aesthetic while resisting knife-slashing, UV fading, and hail damage. The individual interlocking slats are joined by contoured hinge joints that prevent prying while maintaining smooth rotational flexing when rolling into the canister.
Canister volume is often a major drawback of retractable bed covers, but the A-Series incorporates an aerodynamic, compact canister housing measuring just seven and a quarter inches deep. This ultra-compact profile preserves maximum truck bed floor length beneath the canister, allowing you to slide four-by-eight plywood sheets or dirt bikes under the housing. The cover also features a torsion spring drive system housed inside an aluminum tube that provides effortless, fluid retraction with the twist of a latch handle.
Review the key engineering specifications, features, and dimensions of the Roll N Lock A-Series below:
| Design Specification | A-Series Parameter | Competitive Advantage | Owner Benefit |
|---|---|---|---|
| Surface Construction | Powder-coated extruded aluminum | Knife-slash & puncture proof | Maximum cargo theft deterrent |
| Canister Housing Depth | 7-1/4 Inches compact depth | Smallest canister footprint | Preserves under-housing floor space |
| Locking Mechanism | Patented four-point locking system | Locks cover to bed side rails | Multi-point perimeter security |
| Torsion Spring Drive | Enclosed tempered steel spring | Smooth, controlled retraction | Effortless one-handed opening |
| Tailgate Locking Hook | Patented tailgate locking flange | Locks truck tailgate automatically | No separate tailgate lock required |
The integrated tailgate locking mechanism is particularly advantageous: when the cover is closed and locked, a heavy steel flange overlaps the tailgate, securing the truck bed completely without requiring an aftermarket electronic tailgate lock.
Clamp-On Installation, Drainage Plumbing, and Seasonal Lubrication
Installing the Roll N Lock A Series is a straightforward clamp-on process that requires zero drilling on most modern pickup truck beds. The system mounts using heavy-duty aluminum side rail clamps that grip the interior truck bed flange. Precision alignment between the side rails and the canister is vital to prevent slat binding during travel. Using a tape measure to ensure equal width across the front, center, and rear of the bed rails guarantees silky-smooth roller glide.
Effective water management is built directly into the A-Series design. Deep water channels along the side rails collect driving rain and funnel it into the front canister, where two large-diameter flexible vinyl drain tubes direct water through existing truck bed drain plugs to the exterior. To maintain optimal operation over seasons of road grit and winter road salt, truck owners should periodically clean the side rail tracks and spray them with dry Teflon or silicone lubricant, never petroleum grease which attracts dirt.
Examine the routine maintenance tasks and seasonal care tips outlined in the service table below:
| Maintenance Procedure | Target Component | Recommended Chemical / Tool | Frequency |
|---|---|---|---|
| Track Cleaning & Lube | Side guide rails and ball bearings | Dry PTFE Teflon lubricant spray | Every 3 to 6 months |
| Drain Tube Flush | Canister drainage funnels | Compressed air or warm water rinse | Spring and autumn seasons |
| Vinyl Seal Conditioning | Perimeter neoprene rubber seals | UV-protectant rubber conditioner | Bi-annually before summer/winter |
| Clamp Torque Verification | Bed rail aluminum mounting clamps | Hand socket wrench (snug check) | After first 500 miles, then yearly |
Following these simple care guidelines prevents track binding, preserves weatherstrip elasticity, and guarantees that your retractable cover glides smoothly in freezing winter sub-zero temperatures and blistering summer heat alike.
How to Install a Roll N Lock A Series Cover in 4 Steps
Follow this step-by-step automotive DIY guide to clamp, align, plumb, and adjust a Roll N Lock A Series tonneau cover.
Position Canister and Align Guide Rails
Set the compact canister assembly at the front of the truck bed, connect the left and right side guide rails into the canister faceplate, and square the assembly.
Fasten Aluminum Bed Rail Clamps
Install the heavy-duty mounting clamps beneath the bed rails, ensuring uniform width along the front, middle, and rear before torquing clamp bolts evenly.
Route Flexible Canister Drainage Tubes
Attach the two clear vinyl drain hoses to the lower canister fittings and route them through existing factory bed drain holes to exhaust water under the vehicle.
Test Latch Engagement and Apply Dry Lube
Cycle the cover open and closed to verify smooth spring retraction and positive tailgate locking, then spray tracks with dry PTFE silicone spray.
Frequently Asked Questions (8 Questions Answered)
Q1: What is the difference between Roll N Lock A-Series and M-Series?
The A-Series is made of all-aluminum powder-coated slats for maximum puncture resistance, whereas the M-Series features a marine-grade vinyl skin bonded over internal aluminum slats.
Q2: Is the Roll N Lock A Series 100% waterproof?
No tonneau cover is completely submersible, but the A-Series is highly weather-resistant, utilizing channel gutters, weatherstrip seals, and dual drain tubes to redirect 98% of rain outside the bed.
Q3: How much truck bed space does the A-Series canister occupy?
The A-Series features one of the most compact canisters in the industry, measuring approximately 7-1/4 inches deep, leaving substantial floor clearance beneath the housing.
Q4: Does installing a Roll N Lock cover require drilling into the truck bed?
Most applications use a no-drill clamp-on design that attaches directly to factory truck bed flanges. Only minor drilling through plastic drain plugs is needed for drain hoses.
Q5: Can the Roll N Lock A Series lock the tailgate?
Yes. The patented locking mechanism includes a rigid steel flange that hooks over the tailgate, locking the tailgate and cover simultaneously with one key.
Q6: Can I open the cover partially, or must it be fully open or closed?
The A-Series features multi-position latch stops, allowing you to lock the cover fully closed, partially open at preset intervals, or completely retracted.
Q7: What lubricant should I use on Roll N Lock side tracks?
Always use a dry silicone or dry Teflon (PTFE) spray lubricant. Never use grease, oil, or WD-40, which attract dirt and cause tracks to gum up.
Q8: Can you drive with the Roll N Lock A Series in the open position?
Yes, you can safely drive at highway speeds with the cover fully retracted into the canister or locked at intermediate positions.
