Roll-N-Lock M-Series Retractable Tonneau Cover for 2015-2020 Ford F-150 (8' Bed)

One latch, one movement. The M-Series on the 2015-2020 Ford F-150 unlocks at the rear and retracts along its rails into a canister at the head of the 8' bed, opening the whole box rather than the back two thirds of it.

The vinyl-over-aluminum build is the whole M-Series argument: the look of a soft cover, the deck of a hard one, and a matte black finish that does not go chalky the way a painted lid can after a few summers.

LG103M is the long-box part, built for the 8' bed on the 2015-2020 F-150. It is the same cover and the same mechanism as its short-box siblings, just longer, and it uses two extra bed clamps to hold the additional track length steady.

What's Included:

• Cover and canister housing with lid
• Driver and passenger side tracks
• Cargo shield
• Two drain tubes
• Track angles and shims
• Bed clamps, cargo nuts and the full fastener kit
• 1/4" Allen wrench
• 303 vinyl protectant
• Vehicle-specific installation sheet

Features

Locks With Your Tailgate
Roll-N-Lock builds a tailgate extrusion into the rear of the cover. With the cover closed and latched, the tailgate cannot be dropped, so the bed is closed off by the cover and the tailgate together rather than by the cover alone.

Three Latching Positions
A patented ratchet-style latching mechanism holds the deck at three points along its travel. Haul something tall and you can leave the cover part way back and still lock it there, instead of choosing between fully covered and fully open.

Weatherproof Key Cover
The keyed twist latch sits behind a hinged cover over the key slot. It is a small part that solves a real winter problem: rain and snow stay out of the cylinder, so the lock does not freeze shut overnight.

Drains Through the Rails, Not Onto Your Gear
The one-piece vinyl top sheds the weather, and integrated channels and drain tubes route anything that gets past the seal down through the rails and out under the truck.

Vinyl Over Aluminum Slats
Aluminum slats carry the load and the structure; an industrial-grade vinyl skin is laid over the top. You get the flat, seamless look of a soft cover with a hard deck underneath it.

Clamps On, No Holes in the Truck
The rails clamp to the bed rails with the included hardware and the canister sits against the bulkhead. Nothing is drilled into the truck itself. If your bed has a drop-in plastic liner, that liner does have to be trimmed and drilled to clear the canister and the drain tubes, and Roll-N-Lock gives the cut measurements in the sheet.

Fitment & Compatibility

This cover is built for one application: the 8' bed on the 2015-2020 Ford F-150. There is no universal M-Series, so the part number and the truck go together.

Installation

Type: Clamp-on, nothing drilled into the truck  ·  Tools: Phillips screwdriver, 7/16" wrench, tape measure and utility knife; plus a drill with a 1/2" bit and a jig saw if the bed has a drop-in liner  ·  Hardware: Included

The side tracks fix to the Ford F-150's bed rails with the supplied hardware and the canister housing sits against the bulkhead at the front of the bed. No holes go into the truck itself.

If your bed has a drop-in plastic liner, read this first. Roll-N-Lock's sheet for this application has you cut the liner back across the bulkhead and at the tailgate end with a jig saw, then drill five 1/2" holes through it so the canister seats properly and the drain tubes can pass through. The sheet gives the exact measurements. A spray-in liner or a bare bed needs none of that. This is the step people are surprised by, so it is better to know before the box is open than after.

Track spacing is the step that decides whether the cover latches: Roll-N-Lock specifies 59-1/4" inside track to track for this truck, and the cargo shield has notches you use as the gauge. Clamps go to 70 in-lb (8 Nm) at the track angles and 62 in-lb (7 Nm) at the bed clamps. Keep the drain tubes clear of the cab vents. Roll-N-Lock does not publish an installation time for this cover, so we are not going to quote one.

Warranty, Shipping & Returns

Warranty. Roll-N-Lock covers the M-Series with a three (3) year limited warranty to the original purchaser against defects in material and workmanship. The warranty is not transferable. Roll-N-Lock states plainly that it does not warrant against water intrusion, including leaks in normal use, so treat this as a water-resistant cover rather than a sealed one.

Three things in the warranty conditions that catch people out. Never spray lubricant into the tracks, silicone or petroleum based especially, because it attracts grit and Roll-N-Lock voids the warranty for it. Clear snow and ice off the cover before you open it. And if the truck is ever towed from the rear, the cover has to come off first. Clean with mild automotive soap and water only.

Free shipping. This cover ships free to the lower 48 states. It travels as an oversized parcel rather than a freight shipment.

Inspect on delivery. The cover arrives in a long, flat carton that takes the knocks before anything inside does. Check the packaging when it arrives, and if you see damage, note it on the delivery paperwork and contact us straight away so we can put it right.

Compliance. Country of origin: USA. Roll-N-Lock assembles the M-Series in Pompano Beach, Florida from US and global materials. California residents: Proposition 65 warning for cancer and reproductive harm.

Returns. Unused items in their original packaging can be returned within 30 days of delivery. If an item arrives damaged, defective or wrong, return shipping is on us. See our Returns & Refunds Policy, or email support@prestigetruck.com with any question.

About Roll-N-Lock

Roll-N-Lock builds retractable truck bed covers and cargo management hardware at its plant in Pompano Beach, Florida, and is part of the RealTruck group of truck accessory brands. Every cover is assembled in Florida from US and global materials and is backed by a three-year limited warranty to the original purchaser, or five years on the electric E-Series.

The M-Series is the vinyl-topped member of the Roll-N-Lock line. Aluminum slats carry the load and an industrial-grade vinyl skin gives it the flat, seamless look of a soft cover. Step up to the all-aluminum A-Series for a harder wearing deck, add MaxTrak T-slot rails with the M-Series XT or A-Series XT, or move to the key-fob-operated E-Series.

Every Roll-N-Lock cover shares the same mechanism: a torsion-spring drive, a patented theft-resistant hinge between the slats, a keyed twist latch behind a weatherproof key-slot cover, and a tailgate extrusion that stops the tailgate opening while the cover is closed. The deck retracts into a canister at the bulkhead and locks there rather than stowing loose in the bed.

Prestige Truck is an authorized Roll-N-Lock dealer. Every cover we ship is new, in the factory carton, and covered by Roll-N-Lock's warranty direct from the manufacturer.
