Elevators can be more effective at lifting objects than arms because they don’t move the object further away from the robot while lifting. The tradeoff in performance comes with complexity, and often this has kept many teams from making elevator systems on their robots. Our collection of elevator products will help your team make a simple, reliable elevator system that will be sure to elevate your level of play:
Energy chain makes wire management on elevator systems a breeze
Our variety of chain tensioning options let you chain-rig your elevator power
Use a friction brake to hold your elevator in place without stalling your motors
Create your elevator frame with aluminum tubes and gussets
The new Elevator Bearing Blocks simplify the sliding element of FRC Elevators. Instead of requiring 4 gussets for each corner of each stage of the elevator, the Elevator Bearing Block simplifies all those parts down to one easy to assemble block.
Notable features:
Fewer parts and no plates.
Compatible with 1/2”, 5/8”, and 3/4” OD bearings.
Easy to assemble and maintain.
Elevator stages can be assembled much closer together, wasting less space.
Energy chain is the industry standard for cable management, especially when it comes to moving systems. WCP carries both Semi-Enclosed which is useful for elevators and Bi Directional energy, typically used for turrets.
Semi-Enclosed Energy Chain (15mm x 30mm, 1 meter length)
Semi-Enclosed Energy Chain (15mm x 45mm, 1 meter length)
Bi Directional Energy Chain (.625" ID, 3ft Length)
Bi Directional Energy Chain (1" ID, 3ft Length)
WCP offers #25 and #35 chain compatible tensioners, the Spartan style and the TurnBuckle style. Allowing for precise adjustments, preventing any chain slack that can lead to inefficiencies and potential damage.
Do you need a single pulley? A double? A triple? You can have 1,323 pulleys, or even more, all by stacking a single part! Our new stackable pulleys allow you to have as many (or as little) pulleys as you’d like by stacking a single part over and over and over. The stackable pulleys are designed to fit together seamlessly, and are sized such that the outer diameter of a 1/4” polycord cable on the pulley is either 1.625” or 2” to match with our flex wheel sizes.
Cascade Pulley Block
1.625" Pulley (1/4" Groove, Single)
UHMWPE Rope (.125" x 25'ft, Black)
The Ratchet Plate is designed to replace a traditional 1/2" hex wrench, offering a compact and efficient solution for one-way motion control. With integrated #10 clearance holes, it allows for straightforward mounting and easy integration into a variety of FRC mechanisms.
Idler Pulley
Idlers are yet another way to ensure proper tension is present in a system as they can be placed either on inside or outside of the belt loop to provide more contact with the sprocket and decrease slack. Adding an idler to the loop does not affect the ratio and can actually benefit performance if placed near the driving pulley as it allows for more meshing.
Kevlar timing belts are a lightweight and durable material known for its increased durability, improved performance, and reduced maintenance. This makes them ideal for use in timing the operation of moving parts, such as elevators.
The Friction Brake allows you to aid your PID controller in holding an arm, elevator or another subsystem in place or even completely hold your mechanism in place without any motor power!
Easy integration with your design
1.875" and 2" bolt pattern compatibility
Compatible with the Rotation SS Gearbox and WCP Bearing Block
Aluminum tubing is one of the base components of our favorite style of robot construction. Tubing tends to be stronger and stiffer than plate construction due to its shape while still being lightweight because of its hollow profile.
We offer the following sizes in plain and punched tubing with the 1" and 2" Pattern.
2" x 1" x 0.0625"
2" x 1" x 0.09375"
2" x 1" x 0.125"
Our Stub Roller System provides a highly modular platform for teams to create a variety of rollers. Constructed from high-strength aluminum, this system delivers a lightweight yet robust solution for your robot. The stub design allows for easy roller installation and removal by using the stub wrench and the included mounting bolt. We offer pulley end hubs, SplineXL end hubs, and regular end hubs, enabling you to utilize belts and gears for powered rollers, or configure them as idler rollers as needed.
These Stub Roller Shafts feature a #10 clearance hole and come with a pre-installed #10-32 nut on the shoulder end, providing a secure and reliable mounting solution for rollers. This design simplifies roller installation and removal, making swaps faster and less complicated during maintenance or competition.
Hubs Available:
1-1/8" OD Aluminum Stub Roller Hub
20t Pulley w/ 1-1/8" OD Aluminum Stub Roller Hub (5mm HTD)

Popular accessories for the Stub Roller system include the Stub Shaft Wrench, which allows for quick and easy roller assembly or replacement. For roller construction, teams can choose between 1.125" aluminum round tube stock or the lightweight 1.200" carbon fiber variant, depending on their performance and weight requirements.
Our Round Roller System gives teams a modular way to create virtually any kind of roller. This Roller System is available in high-strength aluminum to create a light-weight and robust roller system for your robot.
Cat Tongue Grip Tape is an excellent solution for increasing traction in intake or roller systems without damaging game pieces. Its non-abrasive surface provides strong, reliable grip while remaining gentle on delicate materials, making it ideal for FRC applications where performance and care go hand in hand.
Available in:
Cat Tongue Non-Abrasive Grip Tape (2" WD, 10FT)
Cat Tongue Non-Abrasive Gription Sheet (11" WD, 44")
