Bumpers - Aluminum Clamping Angles

[FRC1346]

In some Q&A replies the aluminum angle has been referred to (parenthetically) as a required element in the construction of bumpers, yet it is not specifically referred to as such in the rules. Yes, it is shown in figure 8.1, however, as we are reminded, the figures are examples, not rules unto themselves.

In previous years the aluminum angle has been optional. Could you please clarify whether the aluminum angle is a required part of bumper construction, or merely a recommended part of bumper construction.

Thank you,

Jason

The required elements of the BUMPER assembly include pool noodles (Rule <R08-B>, plywood backing (Rule <R08-C>) and fabric covering (Rule <R08-D>). The clamping angles are optional, but highly recommended to distribute impact stresses across a larger area and avoid shredding the covering fabric.
