One Toy Set, Endless Structures to Build
TubeLox lets kids design and build their own jungle gym, playhouse, fort, or car, then take it all apart and start again.
One Toy Set, Endless Structures to Build
Build Anything They Imagine
Build Anything They Imagine

With colorful connectors and sturdy tubes, kids can design a car, a house, a rocket ship, or anything else they dream up. Every build starts the same way, with open ended pieces and no set instructions, so imagination leads the way.

Real Play, Not Just Pretend
Real Play, Not Just Pretend

The wheels and panels let kids build cars and rides that actually work, ready for a zip around the house or yard. Dress up play meets real construction, so a firefighter costume and a rolling truck can share the same afternoon.

Sturdy Enough to Climb, Sit, and Play On
Sturdy Enough to Climb, Sit, and Play On

Locking adapter clips hold each structure together, making builds stable enough for kids to sit, climb, or gather around. Whether it becomes a play table or a fort, the connections are built to handle active, hands on play.

STEM Learning Built In
Kids practice engineering, spatial skills, and problem solving with every structure they design.
220 Parts Per Set
Two full Deluxe Sets give kids enough pieces to build large, ambitious projects together.
Locking Connections
Colorful attachment pieces and locking adapter clips keep structures stable during active play.
Social, Shared Play
The scale of TubeLox invites siblings and friends to build, problem solve, and play together.
How to Choose a Modular Building Toy

Not all construction toys are built for the same kind of play, so it helps to think about how your child actually plays before you buy.

  1. Consider the scale of play: Tabletop building sets are great for quiet, seated play, while life sized sets like TubeLox let kids build structures they can sit in, climb on, or ride. Think about whether you want a toy for a table or one that takes over a room.
  2. Check how pieces connect: Toys that lock or clip together tend to hold up better to active play than friction fit pieces that pull apart easily. If your child likes to climb on or ride their creations, sturdier connections matter.
  3. Think about indoor and outdoor use: Some building toys are only meant for a carpeted floor, while others can handle a driveway or backyard. Confirm the material and wheels suit where your child will actually be playing.
  4. Plan for storage and space: Large sets with hundreds of parts need a bin, shelf, or corner of a playroom. Decide ahead of time where pieces will live between building sessions so cleanup stays manageable.
  5. Match the set size to your goals: A single set is enough for smaller builds, while two sets combined allow for bigger, more ambitious projects like a jungle gym or playhouse. If siblings will build together, more parts mean less competing for pieces.
Frequently Asked Questions
What ages is TubeLox appropriate for?

TubeLox is designed as a STEM building toy for active, imaginative kids who enjoy hands on construction play. As with any building toy with small connector pieces, parents should supervise younger children during play.

Can this be used both indoors and outdoors?

Yes, TubeLox is designed to work as both indoor and outdoor play equipment. Many families build structures inside and then move them outside for active play like riding cars around the yard.

How many pieces come in this order?

This listing includes 2 TubeLox Deluxe Sets, each with 220 parts and its own box, for 440 parts total. That gives kids enough material to build larger, more complex structures than a single set allows.

How does shipping work for a set this size?

This product ships from our US warehouse in two separate boxes, each measuring 28 by 18 by 12 inches and weighing 32 pounds. Orders over $100 ship free within the US, and this set qualifies.

What is your return policy if it does not work out?

We offer 30 day returns and our US based customer support team is available to help if you have any questions before or after your purchase. We want you to feel confident about a purchase this size.

Is this toy sturdy enough for kids to sit or climb on structures?

Yes, the tubes connect with colorful attachment pieces and locking adapter clips designed to keep structures stable during active play. This is part of what sets TubeLox apart from toys meant only for flat, tabletop building.
