An optional accessory on many ROGERS platform deck trailers, Center Boards are the decking that sits between the mainbeams on the deck of the trailer. The decking can be either permanently installed (using carriage bolts and floor clips) or loose (held in place with spring hold-downs). Loose Center Boards can then be used with the trailer's side brackets to widen the trailer deck by up to two feet for wider machines.

Located in the center of the rear frame, the Cover Boards provide traction for rollers and tracks, or the Cover Boards can be removed for access to a boom trough for excavators.

Croucher® is the registered trademark name for the front slope design on the platform decks of ROGERS detachable gooseneck trailers. The front portion of the main beams are tapered on the top and bottom for easier loading as though the trailer is "crouching" close to the ground. The beam hooks on the trailer frame are also positioned at or below the front slope profile in order to allow easier loading of rollers and similar machinery.

Deck plate is the loading surface on most drop side deck trailers. It is usually made from 1/4" or 3/8" steel tread plate and takes the place of wood decking to achieve the lowest deck height possible.

A Depressed Cover Plate is a formed plate in the rear frame that is either welded or bolted to the lowered cross members in the "boom trough" or the "bucket pocket". The Depressed Cover Plate provides road spray protection and added storage.

A Detachable Rear Frame is a key feature to ROGERS Modular Series trailers which allows decks of different styles (platform, drop sides, or I-beam) and/or sizes to be interchanged with the same gooseneck and rear frame. ROGERS has two types of Detachable Rear Frames: The traditional Hook & Shaft style and our new Pin & Paddle style. Both types feature easy connection and can be easily shimmed to adjust deck height when needed. The new Pin & Paddle style is also capable of accepting a Deck Extension in order to add to the trailer's deck length.

The Disc Wheel is a style of wheel, steel or aluminum, for mounting tubeless tires. Disc Wheels are available with 8 holes for 17.5 tires, or 10 holes for 22.5 tires; and are hub-piloted, that is, the axle hub is used to align the holes.

Dock Bumpers are an accessory for the rear for the trailer to protect the rear channel and lights from damage when backing up, for example, to a loading dock.

The ROGERS Dolly Link is a special type of Gooseneck Extender that allows a properly designed trailer to be used with a ROGERS Helper Dolly.

On a Tag-Along, the Drawbar is the extension of the trailer's main beams to join at a triangular point in front of the deck. The adjustable pintle eye is attached to the front and connects to the towing vehicle.
