Kolbe Ultra Series

Kolbe’s traditional double hungs are an updated version of a classic style. The sloped sill creates a traditional appearance

and helps guard against water damage. Kolbe’s traditional double hungs open and close smoothly and effortlessly, and the

sash can be tilted in or removed for easy cleaning.

*The Oil-Rubbed finish is a living finish, which means that it will change appearance over time with use.

Clay-colored cam locks are factory-applied to Traditional double hung units as standard. Other finishes available

include White, Beige, Brass, Antique Brass, Satin Nickel, Antique Nickel, Rustic Umber, Oil-Rubbed*, and Matte

Black. For units without finger grooves, sash lift handles in Clay, White, Beige, Brass, Antique Brass, Satin Nickel,

Antique Nickel, Rustic Umber, and Matte Black finishes are available.
