Born in the picturesque valley of Velledalen, nestled within the Sykkylven community, as the eldest son of a farmer, a seemingly unassuming beginning for an actor. However, his fascination with theater was kindled by a local group of youths, who were performing amateur theater productions, captivating Drabløs's imagination.
A few years later, he joined a touring company called The Norwegian Play team, a group of actors and musicians founded by the renowned writer, actress, and manager Hulda Garborg. Garborg was also one of the founders of The Norwegian Theater, established in 1913, and Drabløs was among the original actors. For nearly five decades, he took on numerous prominent roles on that theater, shining particularly as Peter in "Ordet"/"The Word" by Kaj Munk, alongside various roles in the plays of Chekhov and Holberg.
Between 1920 and 1925, Drabløs led his own touring company, and later served as manager at The Norwegian Theater for two seasons.
In film, he primarily played minor parts, often portraying a farmer or an elderly family member. He also appeared in numerous radio plays and was a gifted reader of poetry. One of his final performances was an outstanding portrayal of an elderly man in a TV production of "Bleikeplassen" by Vesaas.
Drabløs passed away in the early spring of 1976, at the age of 93, amidst the serene beauty of Norway's western hills, during the finest period of the year.
