Inside your greenhouse, heat builds fast—and your seedlings start to panic before you even notice.
This aluminum opener stops guessing. Temperature climbs, springs activate, and windows crack open to let heat escape; the air stays alive without you standing there with a clipboard. Wind-resistant springs mean gentle breezes don't yank the window wide; they hold steady, measured, deliberate.
A closer look
Clamp or screw it down depending on your build. It works with whatever frame you've got, asking nothing except to be bolted on and left alone.
