Faster & Safer Wood Window Installation^{46, 47}

The Pella Steady Set interior installation system comes standard on many Pella Reserve and Lifestyle Series products at no additional cost.

Designed Specifically for Builders & Installers

We set out to make every part of window installation as easy as possible. The patented interior installation system is designed for durability and longevity. We rigorously tested the entire system and each component so you can trust it to perform.

Head Stabilizer
Enhanced Stability During Install
The head stabilizer engages with the rough opening header to help temporarily stabilize the unit, eliminating the need for someone to hold the unit from falling inwards prior to fastening.
Flashing Fin
Tear-Resistant Seals for Confidence
The pop-up yellow fin deploys easily after the window is set to help ensure an exterior water barrier after being flashed. A flexible hinge adapts to wall variation and integrated corner seal allows for a continuous seal.
Flip & Click Installation Bracket
High-Performance Structural Attachment
The pre-attached brackets securely attach the window to the rough opening and make an audible click upon reinsertion for install confidence. Simply unclip, flip and click to be install ready.
Sill Shims
Clearance for Foam, Sealant & Tools
The pre-applied sill shims raise the unit 1/4" off the rough opening sill, allowing tools to be easily inserted to manipulate the unit and limiting pinched fingers and damage when leveling.
Shim Guide
Consistent Frame to Sash Reveals
The shim guide comes pre-attached to the jambs of select units and assists the installer by helping to hold shims in the correct location.
