From the Keel Guard website installation instructions
Note: If your trailer is designed with the weight of the boat resting on the rollers or a support beam along the keel, we do not recommend installing a keel protector. If the rollers can be lowered or the side bunks raised to clear the rollers, the Keel Guard adhesive bond will not be compromised.
