24x72 wall caps: one slab, many wall widths
Everything in this collection is the same format: a 24" wide, 72" long, 2" thick slab with an eased (slightly rounded) edge on all sides. We list it as a tread/cap because that is how it gets used: cut down to cap a seat wall, a retaining wall, a pier or an outdoor kitchen counter, or left full width as a step tread. The same piece appears in the 24x72 coping size collection for pool applications and in wall cladding for vertical work.
Cutting a 24x72 slab to cap a wall
Most block or CMU seat walls are 8" to 16" wide. A 24x72 slab rip-cut down the middle gives two 12x72 caps with one factory eased edge each and one fresh-cut edge; for a 12" wall with a 1" overhang on both sides, that works out neatly. A 16" wall takes a 18" cap, which leaves a 6" offcut. Because the slabs are 2" thick, they read as a substantial cap rather than a thin veneer, and the eased edge is comfortable to sit on. Plan cuts so factory edges face the exposed side and cut edges meet at joints.
Colors and finishes
The marble caps come in Ibiza White, Corsica Cream, Bursa White, Ice White, Tundra Grey, Diane Royal and Ocean Blue, in sandblasted or leather finish. The travertine caps cover Ivory, Walnut, Noce, Silver, Silver Alaska, Silver River and Country Classic. Match the cap to the pool coping or paver you are using; every color here has a matching pool coping line, and the coping colors guide walks through the shade differences.
Handling and ordering
A 2" slab this size is heavy; two people and a set of suction cups or a slab clamp are the minimum for placing one. Caps ship flat on pallets by LTL freight, and the product page shows pieces per pallet and pallet weight. Count linear feet of wall, divide by six, and add one extra slab per ten for cuts and breakage.
Frequently asked questions
How do I figure how many 24x72 caps I need?
Measure the total length of wall in feet and divide by six for full-width use. If you are ripping the slab into two 12" caps, each slab covers twelve linear feet. Add one spare slab per ten to cover cuts, corners and breakage.
Can I get a bullnose edge on these caps?
The stock pieces are eased edge only. Bullnose is available on the standard pool coping sizes such as 6x12 and 12x24, but not on the 24x72 tread format. If you need a rounded profile on a wall cap, a fabricator can round the eased edge on site.
Do wall caps need to be sealed?
Yes. A cap is a horizontal surface that catches rain, leaves and drinks, so a penetrating sealer is worthwhile on both marble and travertine. Apply it after the mortar has cured and the stone is fully dry, then reseal when water stops beading.
How heavy is one 24x72 cap?
Heavy enough that one person should not try to carry it. Weight varies by stone, so check the product page, which lists the pallet weight and piece count, and divide to get a per-slab figure. Plan for two people or lifting equipment to set each piece.
