If you're finishing exterior cladding facade products, the outside corner is one of the most visible seams on a siding job. Two outside corner post trim beads are worth comparing: a 4-inch flange version listed at USD 88.79 and a 3-inch flange version listed at USD 99.77. Both come in Grey, are New, and are built to cover the outside corner where siding panels meet. The decision comes down to how wide you want the corner wrap and whether you prefer a longer listed piece.
Quick verdict
The 4-inch Outside Corner Post Trim Bead lists lower and comes with the longer of the two listed lengths, paired with 4-inch side flanges. The 3-inch Outside Corner Post Trim Bead lists higher and takes a slimmer 3-inch flange, with a slightly shorter length. If you want a wide corner wrap and more length for the price, choose the 4-inch; if a compact profile matters more, choose the 3-inch.

Product notes
4-inch Outside Corner Post Trim Bead
The 4-inch Outside Corner Post Trim Bead is the lower-listed-price option in this pairing. Its 4-inch side flanges give you a broader wrap on the outside corner, which helps when siding edges need more coverage. The longer listed length also means fewer pieces to align on taller corners. The trade-off is a more substantial corner profile: the wider flanges add more visible trim, so confirm that look fits your exterior before ordering.
3-inch Outside Corner Post Trim Bead
The 3-inch Outside Corner Post Trim Bead is the higher-listed-price choice, with 3-inch side flanges that keep the corner cover tighter and less bulky. That makes it a good fit for facades where you want the trim to disappear into the siding line. The listed length is shorter than the 4-inch version, so on taller runs you may need an additional piece. The narrower profile is the main reason to accept the price difference.
Final choice by use case
Choose the 4-inch Outside Corner Post Trim Bead if you want the lower listed price, a wider corner wrap, and the longer listed length. Choose the 3-inch Outside Corner Post Trim Bead if a slimmer corner profile is your priority and you are comfortable with the higher listed price.
