Heritage's window product offering includes architectural style, casement awning, horizontal slider
and single hung.
The EH-TW550 is also quick and simple to set up, thanks to its manual horizontal slider
and automatic vertical keystone correction.
The website has a big selection of the mags in a long horizontal slider
with neat and, from the ones I know about at least, really good and accurate explanatory pop-up texts.
Use horizontal slider
or casement windows, which are easily operated from a seated position.
