Finned Weather Strip Brush for Aluminum Window Extrusion

Finned weather strip brush with center fin for aluminum window extrusion, sliding doors and higher barrier sealing applications.

Finned weather strip brush with plastic center fin for aluminum window extrusion

Product overview

Finned weather strip brush is selected when a regular pile seal is not enough for the target window or door system. The center fin helps improve the barrier against air movement, dust and insects while the pile still supports sliding contact. For aluminum extrusion buyers, system window factories and higher-performance accessory distributors, the important specification points are base width, pile height, fin height, pile density and the clearance inside the sliding profile.

How to choose this product

Choose this product when the project needs stronger barrier performance than regular non-finned pile.
Check the sliding gap carefully because fin height should work with the pile instead of folding or scraping inside the track.
Provide extrusion drawings when possible, especially for system windows or heavier sliding door profiles.
Compare sample movement resistance with the final frame before confirming a bulk order.

Sample and order process

Send groove size, sliding clearance, target barrier requirement and old seal photos.
Confirm base, pile and fin dimensions before sample production.
Test the sample in the actual extrusion for movement, compression and visual fit.
Approve final production details, carton labels and shipping marks after sample confirmation.

Packing and shipping

Finned weather strip brush should be packed to protect the fin structure from deformation during handling. Roll diameter, carton size and specification labels need to be confirmed before shipment. For projects with several profile sizes, separate carton marks help avoid confusion during window factory installation.

FAQ

Common buyer questions

When should I choose finned pile?

Choose finned pile when the project needs a stronger barrier than regular pile weatherstrip.

Can fin height be customized?

Yes. Fin height should match pile height and the actual sliding gap.

Do you need drawings?

Drawings or profile samples are strongly recommended for reliable sampling.

Does a fin always improve sealing performance?

A fin can improve barrier performance when the profile gap is suitable, but the size must be matched so it does not create excessive friction.

Can finned weather strip brush be used in sliding doors?

Yes, if the base width and fin height match the door track. Heavy sliding systems should be tested with samples.

What details are most important for a finned strip quote?

Base width, pile height, fin height, color, quantity and profile drawings are the most useful details for quotation.
