Twin thread (Telescopic) screwjack with a handle with the small bracket set, these screwjacks are made in solid brass and laquered to maintain the finish, the twin thread screwjacks have an inner and outer thread that extend together, the advantage to this the screwjack does't protrude out to far keeping the installation neater.
This is the smaller of the 2 handle type screwjacks we stock, both types are most popular on low level windows and skylights that are within reach. The small bracket set is most often used on windows and skylight windows were there is visible frame on the opening vent. The small bracket on the body can be face mounted or mounted down to a deeper frame or ledge you need to ensure the handle is clear of the frame or ledge so you can operate the screwjack.
It is popular to purchase the extended bracket to give the extra height to operate the handle, you can also mix the bracket types if needed. If you need advice please call us
