Good value for bulk purchase

Bought these for a community project. The quality is consistent across the pack. One corner was slightly rough, but nothing a little sanding couldn't fix.

Perfect for screen door repairs

These brackets are exactly what I needed to reinforce the corners of my old screen door. They fit snugly and the plastic feels durable enough to withstand daily use.

Decent but check dimensions

They work well, but make sure you measure your profile thickness first. They were a bit tight on my older aluminum frames, but manageable with some force.

Great reinforcement solution

My screen door corners were sagging, but these brackets fixed the issue immediately. They provide excellent structural support without looking bulky.

Excellent for DIY projects

As someone who does a lot of home maintenance, having a bulk pack of these is a lifesaver. High-quality plastic that doesn't crack under pressure.

5 FAQ

Q: Can these be painted to match a different color scheme?

A: Yes, the matte finish accepts most exterior-grade spray paints designed for plastics. We suggest cleaning the surface thoroughly before painting.

Q: Do these work with vinyl screen frames or just aluminum?

A: They are compatible with both standard aluminum and vinyl screen door frames, provided the internal channel dimensions are standard.

Q: Are these suitable for outdoor exposure in direct sunlight?

A: Yes, these brackets are made from UV-stabilized ABS plastic, making them resistant to fading and brittleness caused by sun exposure.

Q: What size screws are recommended for installation?

A: We recommend using #6 or #8 pan-head screws, approximately 1/2 inch in length, depending on the thickness of your frame profile.

Q: Is there a warranty included with the bulk pack?

A: Yes, all our building material accessories come with a 1-year manufacturer warranty against defects in material and workmanship.
