How to read MORryde cargo tray sizes

MORryde lists tray sizes a few different ways depending on the product line. That can feel confusing when you’re matching a tray to a basement door opening—or trying to see if a cooler or tote will sit between the rails.

Here’s a plain-English guide to CTG cargo trays, SP56 freezer trays, and SP60 utility trays, based on MORryde’s published charts and how these trays are built.

Quick rule: Always measure your door opening and your gear. Charts tell you the tray; your tape measure tells you the fit.


CTG cargo trays (60% extension)

How the part number works

The last four digits of a standard CTG part number are the listed width × length in inches.

Example part # Listed size
CTG60-2348W 23″ W × 48″ L
CTG60-2648W 26″ W × 48″ L
CTG60-3660W 36″ W × 60″ L

Widths commonly run 20″ through 52″; lengths commonly run 36″, 48″, 60″, 72″, and 90″ (90″ trays typically slide out from both sides of the unit).

Listed size = outer dimensions

For CTG cargo trays, the listed width and length are outer dimensions. Nothing on the tray is meant to stick out past those listed outer dims.

Actual overall width is a bit narrower

In practice, the actual overall tray width is about ¼″ less than the listed width, so the assembly can clear a door opening that matches the listed size.

Example: A tray listed as 23″ wide is typically about 22¾″ overall width.

That’s why a “23″” tray can still fit through a roughly 23″ opening—MORryde builds in a little clearance.

Lip height (soft guidance)

MORryde’s sliding-tray materials note that standard cargo trays have about 1.6″ of lip clearance. Floor-to-top-of-lip height is often in the ballpark of roughly 4.3″ on common CTG builds—useful for planning risers or tall totes, but treat that as guidance and confirm on the unit you receive if clearance is critical.

Usable space between the rails (coolers & totes)

Unlike freezer trays, MORryde does not publish a carpet-between-rails usable inside dimension (I.D.) for CTG cargo trays the way they do for SP56 freezer trays.

That means:

  • The listed width is outer, not “how wide your cooler can be.”
  • Rails, carpet, and lip all eat into usable width.
  • We don’t promise a specific cooler or tote will fit without you measuring your tote’s outside width against the usable space on the tray you choose.

Best practice: Measure the outside width of your cooler/tote, then leave a little wiggle room for carpet and rails. If you’re between sizes, size up—or ask us before you order and we’ll help you think it through.

Weight capacity (published): Standard CTG60 cargo trays are listed at 800 lb capacity. Separate CTG80 dual-way 72″ trays are listed at 500 lb.


SP56 freezer trays

SP56 freezer / sliding trays are different: MORryde publishes both outside dimensions (O.D.) and inside dimensions (I.D.) on the chart.

That makes cooler and freezer planning much clearer—you can compare your appliance’s footprint to the I.D., and compare the opening/bay to the O.D.

Examples from the Sliding Tray Flyer

Part # Style O.D. (W × D × H) I.D. (W × D × H)
SP56-115 Front pull 37.6″ × 21.6″ × 3.5″ 31.42″ × 19.7″ × 3.5″
SP56-132 Side pull 18″ × 26.5″ × 3.5″ 14″ × 24.8″ × 3.5″

SP56-203 (hidden / under-floor style): tray is 26.3″ W × 16.1″ L × 2.7″ H, with adjustable brackets for framing spacing about 20″ L (min) – 26″ L (max).

SP56 trays are commonly described with 200% extension (front/side pull styles) or 70% extension (hidden tray), durable powder coat, and dual latches on the heavy-duty freezer slides—always check the specific product page for capacity and extension.


SP60 utility trays

For SP60 utility trays, the dimensions on the chart are inside dimensions.

MORryde’s flyer note: add 2″ for overall width and 2″ for overall depth to get outside dimensions.

Example (inside, listed) Approx. outside (add 2″ W and 2″ D)
SP60-041 — 14″ × 14″ × 2.75″ ~16″ × 16″ overall footprint
SP60-044 — 24″ × 24″ × 2.75″ ~26″ × 26″ overall footprint

Capacities on the chart typically range about 250–300 lb depending on part number. Confirm on the product listing.


CTG vs SP56 vs SP60 — at a glance

Family What the listed size means Published I.D.? Best for
CTG cargo trays Outer W × L (from part #) No carpet-between-rails I.D. published Basement cargo, totes, generators, general gear
SP56 freezer trays Chart shows O.D. and I.D. Yes Freezers / fridges / cargo you need past the slideout
SP60 utility trays Chart shows inside dims; +2″ W and +2″ D for outside Inside is what’s listed Generators, LP tanks, compact utility storage

How to measure before you buy

  1. Door / bay opening — Measure the clear width and depth of the compartment opening (and watch for hinges, gas struts, and door seals).
  2. Tray listed size — Match CTG listed outer size to that opening, remembering ~¼″ less actual overall width on CTG.
  3. Your gear — Measure the outside of coolers, totes, freezers, or tanks.
  4. Usable space — For SP56, use the published I.D. For CTG, don’t assume listed width equals tote width—leave margin for rails and carpet.
  5. Lip / risers — If your compartment has a tall lip, look at the cargo tray riser kit options so the tray clears when extended.
