Choosing replacement corner caps for a pontoon boat deck often comes down to matching the old cap's rounded profile. In the deck hardware seating covers aisle, two silver gray aluminum 2-packs are the main contenders: the 2 Pcs Pontoon Boat Aluminum Deck Corner Caps and the 2Pcs Pontoon Boat Aluminum Deck Corner Caps (USA). Both are described as fitting 90° rounded corners, and both are explicitly not suitable for 90° right angles.
A deck corner cap's dimensions are not adjustable, so a cap that's too tall or too short won't sit flush. The first filter is the shape of your existing corner; the second is the listed size range. The two sets do not share the same height range, so measuring before you buy is the most important step.
Quick verdict
If you need a taller listed cap, choose the higher-priced set. If you prefer a lower listed price, choose the lower-priced set. The tiebreaker is whether your old corner caps fall closer to the taller range or the shorter range. Neither set is meant for 90° right angles, so check your corner shape before ordering.

Product notes
2 Pcs Pontoon Boat Aluminum Deck Corner Caps Boat Deck Hardware silver gray
This set is described as classic style, and the included components are two corner caps. It is the larger of the two listed profiles, and it is also the more expensive option. The classic descriptor gives it a slightly different visual positioning from the other set, which may matter if you're trying to match the look of your boat's existing hardware. The two-piece count is confirmed, so you know exactly what you're getting in the box. The extra cost is the main thing to weigh before choosing it. If you need a taller cap and don't mind paying more, this set is the straightforward match.
2Pcs Pontoon Boat Aluminum Deck Corner Caps Boat Deck Hardware silver gray USA
This set is described as powder-coated aluminum with seawater corrosion resistance, a detail that can be valuable in a marine environment. It also carries a no-screw, no-adhesive installation note, which can make the replacement process simpler. The trade-off is a shorter listed profile, so it won't match if your original cap is the taller version. The listing includes a reminder to measure your original caps before purchasing, which reinforces the need to confirm the fit. If your existing corner caps fit within the smaller height range, this is the more budget-friendly pick.
Final choice by use case
Measure your existing corner cap first. If the height lands near 3-5/8\" and the top near 4-3/16\", pick the 2 Pcs Pontoon Boat Aluminum Deck Corner Caps. If the height is closer to 3-1/8\" to 3-3/16\" and you want the lower listed price, pick the 2Pcs Pontoon Boat Aluminum Deck Corner Caps (USA). For most replacements, the size range is the deciding factor: a cap that is too tall will overhang, while one that is too short leaves the corner exposed. Compare your measurements with the numbers in the table, then let the $11.31 price spread guide the final pick.
