Deltana BC218R Ball Catch with 2-1/8" Strike, Round Corners

That's exactly what it's for. The BC218R is a light duty catch meant for doors where there is no latch, so a closet door, a pantry door, or a dummy-trimmed door stays shut against a spring-loaded ball rather than a latchbolt. It's adjustable, so you can dial the ball tension up or down after the door is hung and the door settles. For an entry door or anything carrying a lockset duty cycle, this isn't the part.

Both halves of the Deltana BC218R are 2-1/8 inches: the catch body is 2-1/8 and the strike plate is 2-1/8, with round corners on the strike. Round corners means you can rout the strike mortise with a router and a bit and leave the corners as they come, no chisel work to square them out. Bore the door edge for the catch body and mortise the jamb for the strike.

No. The BC218R is a residential, light duty catch, and it's built for doors with no latch. Commercial traffic doors, corridor doors, and unit entries need a rated latching device, not a friction catch. Use it inside the unit on closet, linen, and pantry doors, which is where property managers actually run into it.

The Orca Hardware 70DR Series Drive In Ball Catch with Radius Strike is the closest peer, since it is also a ball catch supplied with a radius (round corner) strike. The Deltana BC218R is a solid brass ball catch with a 2-1/8 inch round corner strike, adjustable, intended for light duty doors with no latch. Both are round-corner strike ball catches, so either drops into a door and jamb already prepped for a radius strike plate rather than a square corner one. The difference is the finish program: the BC218R is offered in PVD Polished Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, Brushed Chrome, Polished Brass, and Antique Brass.

They serve the same function but are not prepped the same way. The Delaney Drive-In Ball Catch and the Orca Hardware 70DR Series Drive In Ball Catch are drive-in style, which means the catch body is driven into a bored hole in the door edge. The Deltana BC218R is supplied with a 2-1/8 inch strike with round corners and matching screws. If the door edge is already bored for a drive-in body and the jamb has no mortise, a drive-in unit matches that prep; if the opening is being prepped fresh or the existing jamb plate has radius corners, the BC218R strike suits it.

No. The Deltana BC218R is designated residential and is designed for light duty doors where no latch is present, so it suits closet, pantry, and French doors rather than a traffic-bearing entrance. The Delaney Drive-In Ball Catch, the Emtek 8802 Door Ball Catch, and the Orca Hardware 70DR Series ball catch are all ball catches as well, meaning none of them is a substitute for a latching or locking device on a commercial opening. For an entrance door the correct part is a latch or lockset, not a ball catch of any brand.

Everything ships together. Each BC218R is packed in an individual poly bag with the strike plate and matching screws, so one unit per opening is all you buy. Price and packaging are per each. Nothing else is required to complete a standard install beyond boring the door and mortising the jamb.

A ball catch like the BC218R mounts in the top or edge of the door and drops a spring-loaded ball into a strike, which is the usual answer on light duty doors with no latch, including pairs of closet or French doors where you want a clean edge and no visible hardware when the door is shut. The tension is adjustable, so on a pair you can set each leaf independently. If you need the door to hold harder or to self-align a warped leaf, a roller catch is the other direction to look. Deltana's own drive-in style alternatives, plus the Emtek 8802 ball catch and the Orca Hardware 70DR drive-in ball catch with radius strike, cover the same job in different mounting styles.

Solid brass, not a plated pot metal body. That matters on a catch because the part that wears is the ball housing and the spring seat, and a brass body threads and adjusts without stripping the way a die cast one will. It also means the finish is applied over brass, so a polished or oil rubbed finish ages rather than flakes.

Nine finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. If you're standardizing a building or a whole floor of units, the PVD Polished Brass is the one to look at for a brass look that holds up to handling better than a lacquered polished brass. Only the strike plate shows once the door is closed, so match the strike to your hinges and knobs.

The BC218R is adjustable, so tension is a screwdriver fix rather than a new part, as long as the catch and strike are still lining up. If the door has dropped and the ball is no longer centering on the strike, reset the strike plate instead. When you are replacing an older catch, measure the existing mortise first: the BC218R uses a 2-1/8 inch body and a 2-1/8 inch round corner strike, so it drops into that prep and not a smaller one.

A drive-in catch, like the Delaney Drive-In Ball Catch or the Orca 70DR drive-in with radius strike, is hammered into a single bored hole in the door edge with no faceplate mortise, which is quicker on volume work. The Deltana BC218R comes with a 2-1/8 inch round corner strike plate for the jamb and a matching 2-1/8 inch catch, which gives you a finished plate showing on the jamb in a matched finish. If you are matching visible hardware in a nicer opening, go with the plated version; if the catch is buried in a closet nobody looks at, drive-in is faster.

The Delaney Drive-In Ball Catch and the Emtek 8802 Door Ball Catch both do the same job as the Deltana BC218R: hold a light duty door closed where there is no latch. If the catch is on an inswing closet or pantry door where the hardware is barely seen, any of the three serve the same function. Where the BC218R differs is that it is solid brass and comes packed in an individual poly bag with the strike plate and matching screws, so the plate and fasteners arrive with the catch rather than being sourced separately.

The Deltana BC218R covers nine finishes across one model: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. That range lets one part number carry units with brass, bronze, nickel, chrome, and black hardware without changing catch models between doors. The Emtek 8802 Door Ball Catch and the Delaney Drive-In Ball Catch are alternatives in the same ball catch family if a unit is being matched to those lines specifically.

Both are door ball catches for holding a light duty door closed. The Deltana BC218R is solid brass, adjustable, and ships with a 2-1/8 inch round corner strike plate and matching screws in the bag. The Emtek 8802 is Emtek's ball catch, so it is the one to pick when the rest of the door hardware on the opening is Emtek and the finish needs to match that line. Adjustability on the BC218R means the ball tension can be tuned after the door is hung rather than being fixed at install.

Sold each, one per opening, with each catch bagged individually with its own strike plate and screws. So a 40 door order is 40 units and nothing else to add to the line. Sticking to a single model and one finish across the building keeps the maintenance closet down to one spare part instead of a drawer of mismatched catches.
