The Weather Guard 114-5-01 is the earlier-generation full-size extra-wide aluminum gull-wing cross box, offered here as the proven, value-priced alternative to the current 1Key latch update. It carries the trusted EXTREME PROTECTION locking system, with a tamper-resistant retracting lock and an automotive-style rotary latch on each of the twin gull-wing lids, so you get smooth one-touch access from either side of the bed and solid break-in protection that has held up on work trucks for years. The finish is a deep gloss black ARMOR TUF powder coat that pairs with dark trim and blacked-out wheels, wipes clean easily and shrugs off sun, salt and jobsite abuse. Mounted across the bed rails behind the cab, the box opens through two independent lids for 15.3ft³ of secured, weather-sealed storage. A five-piece welded aluminum diamond-plate body with a reinforced C-channel front keeps it strong yet light, and a full-perimeter D-shaped weather seal locks out rain and dust.

Features

Welded Aluminum Diamond-Plate Build
A five-piece welded aluminum diamond-plate body with a reinforced C-channel front panel keeps this box strong yet light. It resists jobsite abuse and road salt without adding the weight of a steel box. This one is finished in gloss black ARMOR TUF powder coat.

Gloss Black ARMOR TUF Finish
The deep gloss black ARMOR TUF powder coat lays down a wet-look shine that ties into blacked-out trim, dark wheels and factory paint. Baked on hard, it fends off scratches, corrosion and UV fade so the box still looks sharp seasons down the road.

EXTREME PROTECTION Locking System
Twin gull-wing lids each carry a tamper-resistant, retracting EXTREME PROTECTION lock and an automotive-style rotary latch for smooth one-touch opening from either side of the truck.

Full-Perimeter Weather Seal
A memory-resistant D-shaped, multi-ridge weather strip runs the entire lid perimeter to keep rain, dust and debris off your tools, so your gear stays dry and ready in any weather.

Dual-Lid Gull-Wing Access
Two independent gull-wing lids open from either side of the truck, so you can reach tools from whichever side you are standing on without walking around the bed. Each lid operates and locks on its own.

Crossover Fit With Bed Clearance
Suspended across the two bed rails behind the cab, the box leaves usable space underneath for longer cargo, and a 12V access port feeds lights and electrical add-ons. A removable divider tray sorts smaller tools and hardware up top where you can reach them.

Fitment & Compatibility

Truck Class	Example Trucks	Fit
Full-size 1/2-ton	F-150, Silverado/Sierra 1500, Ram 1500, Tundra, Titan	✓ Yes, spans the top bed rails behind the cab
Full-size 3/4-ton and 1-ton	F-250/F-350, Silverado/Sierra 2500/3500, Ram 2500/3500	✓ Yes, ideal application
Mid-size and compact	Ranger, Colorado, Tacoma, Frontier, Maverick	✗ No, not designed for smaller beds

Fit guidance: Crossover, or saddle, boxes mount across the truck bed on top of the two bed rails just behind the cab, so the box straddles the bed and leaves the bed floor open. At about 72" wide this size fits standard-width full-size pickups, and because it sits on the rails rather than the bed floor it works with short, standard and long beds on those trucks. This is an extra-wide box, so it needs a full-width full-size bed and will reduce side-to-side reach past the box. Always measure your bed rail width and check clearance behind the cab before ordering. It is not designed for compact or mid-size trucks.

Set the gull-wing box across the two bed rails behind the cab and center it left to right, then hook the included clamps under each bed rail and tighten the hardware evenly so the box sits flat and both lids seal. Because the box is wide and opens from both sides, have a second person help lift and hold it while you clamp it down. Follow the Weather Guard installation instructions for exact clamp placement and torque.

Weather Guard Truck Box Hardware Installation Guide

Weather Guard's official hardware video zooms in on the clamp and bolt kit that secures its truck boxes to the bed rails without drilling. It is a helpful close-up companion to the full box install and shows how the mounting brackets hook under the rail lip and tighten down. Use it alongside the printed instructions that ship with the box.

Weather Guard Truck Box Lineup and 1Key UltraLock

This official Weather Guard overview tours the current truck box lineup and the 1Key UltraLock security system that runs across it. You see how one coded key can open every Weather Guard box on the truck, from saddle to lo-side to hi-side, with a pop-up red button that tells you at a glance whether a box is locked. It highlights the sloped, reinforced lids and the ARMOR TUF powder coat that let these boxes shrug off weather and jobsite abuse. If you run more than one box, or a whole fleet, it shows why keying everything alike saves time every day.

How to Replace the Lid on a Saddle Truck Box

Weather Guard's step-by-step guide to taking the lid off a saddle truck box and fitting a replacement. It covers the hinge and strut hardware that carries the lid, which is the part that takes the abuse on a box that gets opened twenty times a day. Keep it bookmarked rather than watching it now. It is the reference you want the day a lid gets damaged on the job, and it comes straight from the manufacturer so the hardware and the sequence are correct.

Frequently Asked Questions

Straight answers on specs, fit and support

Will the 114-5-01 fit my truck?

It is a full-size extra-wide crossover, or saddle, box that mounts across the top bed rails behind the cab, so it fits full-size pickups such as the F-150, Silverado and Sierra 1500 through 3500, Ram 1500 through 3500, Tundra and Titan. It needs about 72" of rail-to-rail width. Measure your bed rails and check clearance behind the cab first, and note it is not designed for compact or mid-size trucks.

Does it require drilling to install?

No. The gull-wing box ships with under-rail clamps and hardware, so it mounts without drilling into your truck. Most installs take about 20 to 30 minutes and go easiest with two people to lift and hold the box while you clamp it down.

How does this cross box lock and open?

This is an earlier-generation Weather Guard cross box with twin gull-wing lids, each using a tamper-resistant retracting EXTREME PROTECTION lock and an automotive-style rotary latch. That gives smooth one-touch opening and solid break-in protection from either side of the bed.

Does the gloss black finish hold up to sun and weather?

It does. The gloss black ARMOR TUF powder coat is a hard, UV-stable, corrosion-resistant layer, and the full-perimeter D-shaped seal keeps rain and spray out of the box. Season after season of loading and highway grime, it resists chipping and fading and holds its wet-look shine.

Is this an earlier-generation box, and why does it cost less than the current model?

Yes. This is the earlier-generation 114 gull-wing box, built around the proven EXTREME PROTECTION retracting lock and automotive rotary latch rather than the current 1Key latch update. The five-piece welded aluminum diamond-plate body, twin gull-wing lids, weather seal and no-drill mounting are the same trusted design, so you get the same everyday performance at a lower, value price.

What is it made of and how big is it?

This earlier-generation gull-wing box is five-piece welded aluminum diamond plate under a gloss black ARMOR TUF powder coat. It measures 72"L x 27-1/2"W x 18-1/2"H, holds 15.3ft³ opened by twin lids, and ships at about 92 lb, so it stays lighter than steel at a value price.
