Description:
The Benchmark LB™ bridges the gap between a flatbed and a service body. Two large front boxes and a pair of rear fender boxes give your tools a dedicated home, without sacrificing too much deck space for materials and equipment. Its tapered tail and plate headache rack round out a design that's as hard-working as it is clean. From mechanics and fabricators to plumbers, electricians and linemen, the Benchmark LB™ is ready for whatever the job throws at it.

What files are included with my plans?
What files are included with my plans?
Every set of plans includes a detailed .pdf build plan and a .pdf bill of materials. Upgrade to the Fabricator's Package to add .dxf CNC cut files, or to the Manufacturer's Package to get all of the above plus a .step 3D model file.
Will the cut files work with my plasma table or laser?
Will the cut files work with my plasma table or laser?
Yes. The .dxf format is the industry standard and works with the vast majority of CAD/CAM software used by CNC plasma tables and lasers. If your machine needs a different file type, additional specialty formats are available upon request. Just contact us.
Can I build more than one bed from a set of plans?
Can I build more than one bed from a set of plans?
Absolutely. There's no limit. Build as many beds from a single set of plans as you'd like, including beds you build to sell.
Can I share the plans with someone else?
Can I share the plans with someone else?
Plans may be shared only with those directly helping you build, such as your employees, coworkers, or a third-party shop manufacturing parts for you. Sharing or distributing the plans outside of your build team, or reselling the files, is strictly prohibited.
How fast will I get my files?
How fast will I get my files?
Instantly. As soon as you complete checkout, you'll receive an email with a download link to a folder containing all of your files.

What if I get stuck mid-build?
Just reach out to us for tech support. Most issues are quick fixes, and we're happy to walk you through any part of the plans.
Do you offer refunds?
Do you offer refunds?
Because our plans are digital and delivered instantly, all sales are final. However, if a set of plans contains an error that affects how the bed is built, we'll issue a full refund. (Minor typos, such as in a title block, don't qualify.)
