Bumper Mount Info
The Plummer Industries Bumper Mounts offers a reliable, modular, and rule-compliant solution for securely attaching bumpers to FRC robot frames. Designed for ease of use, strength, and quick removal.
Bumper Mounts
The Bumper Mounts are based on a ball lock mechanism that requires activation for both installation and removal to prevent accidental detachment and provides a tensile strength of over 500 pounds. To prevent rust all steel parts in the bumper mounts are black oxide coated to allow teams to reuse them from year to year.
Our Bumper Mounts were designed for and tested on robots during the 2022 single day event format. Where match turn arounds were in the 4-7 minute timeframe and every second of pit time mattered. The 1-2 minutes saved from changing bumpers makes a big difference in those quick turn arounds.
The Horizontal system, for teams that use four individual bumpers, allows teams to keep hands completely outside of the frame perimeter when installing and releasing bumpers. This enables teams to design and build mechanisms the full width of the robot while maintaining easy access to the bumper mechanisms. So no more impossible, time consuming reaching around the mechanisms to get to bumper pins or latches. The horizontal system requires a simple hex key or t-handle to activate.
The Vertical system is for teams that use the two C’s or ring design bumpers. Just reach over the bumper and press an easy to access button. Steel brackets are available to support the corners of these types of bumpers. Vertical Bumper Mounts provide the same quick release but without the need for a tool. Adjustable versions are available for when more than one mount is on a bumper segment.
These systems can be mixed and matched to meet your team's specific needs.
