Abstract
Fenestration units that include slide mechanisms that operate the unit through linear motion. Slide mechanism designs include a handle, a slide member coupled to the handle, and a linear rail along which the slide member is slidably received such that the slide member is operable to slide in a linear motion. The slide member includes an attachment structure for operatively coupling with a drive belt to transfer linear motion through a transfer mechanism to a drive mechanism of the unit. The attachment structure is attached to the drive belt such that a position of the attachment mechanism along the length of the drive belt may be adjusted by a user.

A fenestration unit comprising:
- a frame;
- a panel coupled to the frame such that the panel is movable between an open position and a closed position;
- a drive mechanism coupled to the frame and operable to actuate the panel between the open and closed positions;
- a transfer mechanism including a drive belt having a length including a first portion and a second portion along the length of the drive belt;
- and
- a slide mechanism including a handle, a slide member coupled to the handle, and a linear rail along which the slide member is slidably received such that the slide member is operable to slide in a linear motion, the slide member including an attachment structure for operatively coupling with the drive belt to transfer the linear motion through the transfer mechanism to the drive mechanism, the attachment structure being attached to the first portion of the drive belt and releasably attached to the second portion of the drive belt such that a position of the attachment mechanism along the length of the drive belt may be adjusted by a user.
