Thank you for using the Jiskha Homework Help Forum. Yes, "bundle" is a noun and "protruding" is a gerund, used as an adjective in this sentence.
You're right. The word, "bundle," is used as a noun.

The word, "protruding" is a present participle, used as an adjective to modify "bundle."

Note: Gerunds are only used as nouns. Participles are used as adjectives.
