**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.

## Layout and dimensions

{% hint style="warning" %}
Horizontal bumper mounts only prevent the bumper from coming off and sliding. You still need to "locate" each bumper segment to prevent them from spinning. See our guide HERE
{% endhint %}

## Basic Installation

#### Tool list

* Drill
* Hammer
* 5/16 Drill bit
* 5/8 Drill bit or hole saw
* 1/8 or ¼ Drill bit for access hole
* Measuring tape or calipers
* Pencil or marking tool

Straws are designed for use with the Horizontal mounts to allow faster activation of the mounts with the tool.&#x20;

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.plummerindustries.com/bumper-mounts/overview/horizontal.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
