What size opening does a 60-by-80-inch door need?

The door is 60 inches wide and 80 inches high, and the 4-9/16-inch jamb suits a standard 2x4 framed wall. The rough opening needs to be slightly larger than the unit to allow for shimming and squaring.

Does the Low-E glass help with heat and fading?

Yes. Low-E coatings reflect part of the sun's heat and block most UV, which reduces cooling load and fabric fading. It still lets visible light through, so the room stays bright.

What lock does it come with?

It uses an ASSA 2002 lock case, a multi-point mechanism that engages the frame at several points. That is sturdier than a single latch and harder to force.

Can the grilles be removed?

No. The grilles sit between the panes, so they are sealed in and cannot be taken out later. Choose the grille look only if you want it permanently.

Is this a left-hand or right-hand door?

It is specified as left-hinged. Confirm the swing direction against your opening before ordering, because reversing it is not a simple swap.

Is this a good value for a double patio door?

This model includes an upgraded ASSA 2002 lock case and Low-E glass, which are often extra-cost options on basic doors. Compare it against other pre-hung double units that include multi-point locking hardware.
