What is clear opening size for a cavity slider?

Clear opening size is the finished walk-through opening that remains after the cavity slider door and jamb are installed. It is the usable opening width that people pass through.

When should I use clear opening size to order a cavity slider?

Use the clear opening size option when you already know the finished opening you want to achieve. This option is useful when the final walk-through width is more important than the actual door leaf or frame size.

Is clear opening size the same as door size?

No. Clear opening size is not the same as door size. The door leaf is larger than the clear opening because part of the door overlaps the jamb and slides into the cavity.

Can Premium Sliding Doors help me choose the correct size?

Yes. Premium Sliding Doors can help you choose the correct cavity slider size based on your clear opening, door type, wall framing and project requirements.

Do clear opening sizes apply to single and double cavity sliders?

Yes. Clear opening sizes can be used for both single and double cavity slider systems. The final system selection depends on the desired opening width, wall space and door configuration.
