Buying Guide
What size do I need? Measure length, width, and height of your blinds. For tall doors, 82.5 inches is common, while 46.5 inches suits standard panels. Do I want light control or blackout? Choose slats with UV resistance for sun exposure and consider a cordless system for child safety. Is replacement easy to install? Look for slats with standard oval holes and included mounting hardware. Should I buy in bulk? If you have multiple doors or large windows, bulk packs reduce the chance of mismatched slats and simplify replacements. Do these slats work with my existing clips? Confirm clip compatibility and hole alignment before purchasing.
Durability matters. UL-rated UV resistance helps prevent cracking and fading, extending the life of the blinds. For sliding doors and patios, ensure the slats are wide enough to cover the opening and that the panel height aligns with the door frame. If energy efficiency is a goal, consider blackout or heavy-duty fabrics that reduce heat transfer. Always compare products by material, length, and width to ensure a consistent look across replacements.
