- Color: Black
- Material: Rubber
- Brand: ESSENTIALLY ENGINEERED
- Product Dimensions: 4.5″L x 4.5″W x 6.25″H
- CUP HOLDER EXPANDER FOR OVERSIZE BOTTLES/MUGS: The 4, rubber tabs keep most oversize (3.4”-3.8”) bottles or mugs securely in place. Perfect for certain versions of Hydro Flask, YETI, RTIC, Nalgene, CamelBak, Klean Kanteen and more (does not fit 14oz or 46oz YETI Ramblers). Please compare bottle dimensions to provided product dimensions before purchasing.
- 3-RING EXPANDABLE BASE: Adjustable base has an expandable diameter from 2.5″-3.75″. This allows the adapter to stay firmly in place, regardless of how rough the terrain gets. Please compare your vehicle cup holder to this product before purchasing. This model works best in cylindrical cup holders. It does not work well in most square cup holders or cup holders that are recessed into the console.
- SLOT FOR COFFEE MUGS: The 1 inch slot is integrated into the design so coffee mugs will fit with ease. This is perfect for the popular YETI 24oz Rambler (14oz Rambler does NOT fit). Please compare dimensions of desired coffee mug to the product dimensions before purchasing.
- EASY INSTALLATION: Just hold the base and twist the top, the base will then retract or expand. Comes with instruction card.
- UNIVERSAL: Fits in almost anything with a cup holder; such as vehicles, boats, RV’s, UTV’s, etc. However, some cup holder designs will not work. PLEASE REVIEW THE PICTURED DIMENSIONS TO ENSURE A PROPER FITMENT BEFORE PURCHASING.

The cup holder works great! I never had a place for my big Yeti until now and it fits like a glove.

Great in the truck

Item as described, easy install. Seems very sturdy but haven’t done any trails with it yet. All of my containers fit except the 14Oz rambler which I was bummed by but went back to read the description and it doesn’t state it fits so I’d have to buy the one meant for the 14Oz separately if I want.

I use a boot on my water bottle and every time I pulled my drink out the cup expander would come with it. I tightened it and it wouldn’t stay.EDIT: Company reached out to try to resolve the issue, but unfortunately it is a compatibility issue with my 2021 Mazda CX-5.
