This Coroplast loft BASE ONLY is 12.5" x 27.5" x 6" sides and made from 4mm-thick corrugated plastic and is designed to be used with our Cagetopia grids (14" square) with connectors. Grids and ramp are NOT included with this item. This Narrow Loft size (1x2 grids) is designed to be used with one of our special Portal Grids on the floor of the loft for an 'attic-style' entrance where the ramp comes up through the floor. This base is professionally cut and scored and includes reusable, plastic rivets to secure the corners. Assembly should also include another Portal Grid vertically at the entrance in order to allow the ramp (not included here) to swing up and down and be easily removed.

The inner edge of the Coroplast is protected with our edge protectors to help dissuade chewing.

Coroplast Only for our Narrow Loft of our Recessed Ramp Design

Coroplast is cut and scored for our 1 grid by 2 grid narrow loft with our recessed ramp. This item is JUST the Coroplast base with its rivets. 

If you need the GRIDS and RAMP as well, please see this item for the complete Narrow Loft.

Coroplast Base Includes

  • 4mm Coroplast bottom in your choice of 16 colors!
    The base is pre-cut and pre-scored with pre-punched holes to secure flaps using snap-in plastic rivets (not tape). Coroplast base is creased and folded for shipping, which creates an indented "crush" line. This does not affect the functionality of the cage and is behind the grid wall when assembled.
  • Rivets for fastening all coroplast flaps

Our Cagetopia-brand Grids have stayed the same over the years as we have many hundreds of thousands of C&C cage owners (DIY and customers) that depend on the original sizes and the best quality grids and connectors.

Supplying your OWN GRIDS?

Or mixing in different grid sources or vendors? No 14" grids are the same anymore. Please review:

  • Many 14" grids are NO LONGER COMPATIBLE
  • Grid Vendors are now ALL DIFFERENT from each other
    Especially on Amazon, but also Bed, Bath & Beyond, Target, etc.
    • DIFFERENT CONNECTORS: gap spacing (space between grids) can be different (standard = 3/8") and that matters.
    • Grid Size: 14" exactly is required -- NOT 12" or anything else
    • Grid Wire Gauge (thickness): Grid vendors adapt their connectors to their wire gauge, which is typically thinner than ours (4mm = 3 pennies), so they won't work well together, if at all -- too tight or too loose.
    • Inner Grid-hole Size (safety-related):
      NO INNER HOLES BIGGER than 1.5" or you risk your guinea pig's head getting stuck and strangling. In a 14" grid, there should be 9 holes by 9 holes -- never less.
  • Using only Zip Ties (no connectors) is NOT RECOMMENDED.
    Some people complain about using the connectors. They are using NON-Cagetopia connectors. Ours work great and are easy to snap in, while being strong and stable.
    • Zip ties alone ARE NOT STRONGER as compared to using Connectors WITH zip ties (not opinion, engineering fact).
    • Many Cagetopia products will NOT be compatible for fit without using the connectors.
    • The fit of the coro inside the grids will be different.

Trying to save a few dollars now on purchasing grids separately could be a frustrating, if not an expensive, decision later.

All these things MATTER on CAGE BUILDING.

If you buy one vendor's grids today and try to mix in a different vendor's grids from Amazon tomorrow, odds are high they may not be compatible with each other or our Cagetopia Grids.

I purchased navy blue coroplast bases for my 2x3 guinea pig cage along with a ramp. I had already made white bases and tried many attempts to make a ramp but had no success on a making a safe ramp. I placed an order for fleece flippers from and didn't think my measurement were correct for the perfect fit for the flippers. I'm so glad I purchased these bases!! My measurements were off because it's easy to see that my piggy has more room to run :) I had originally made a loft for an outset ramp but when I put the ramp in her cage she had a tight squeeze to get up her ramp. She didn't show any struggle running around and flying up the ramp but she is only a couple months old. I hadn't cut the new navy loft because I was thinking of making this outset loft into an inset loft but I didn't know how. I emailed Sue and she was very quick to respond with and diagram with a note with what not what to cut. Nervous as I was, because of my track record with cutting coroplast, I had many questions. Sue recommended that I talk with Alan and he can give me a better description on how to convert my piece. Alan has patients of a Saint! He walked me through it clearly step by step. Sue and Alan provide QUALITY products with EXCELLENT customer service! My only regret was not buying the cage from them to begin with.
