BEST DLS-1-626 – Frequently Asked Questions

1) What is the BEST DLS-1 double lipped strike actually for?
The DLS-1 is a frame strike for center hung doors set with a 1/8 inch inset, and the double lip is what lets the door swing both ways without the leading edge chewing up the frame. It is a strike, not a hinge or a pivot, so it is the frame-side piece that receives the latch bolt. Ordinary single-lip ANSI strikes only protect one swing direction, which is why they get destroyed on a bi-directional opening.
2) Will the DLS-1 strike accept my existing bored lock latch bolt?
The cutout is 1-1/4 x 11/16 inches, which is the ANSI cutout for heavy duty bored type locks. If the cylindrical lockset already on the door was prepped to that standard ANSI strike cutout, the latch drops straight into the DLS-1. A mortise lock with a larger latch and auxiliary deadlatch face will not sit in that opening.
3) What frame cased opening does the DLS-1 need?
It is built for a 5-3/4 inch cased opening, and that is the only size offered, so the frame prep has to match. All three finishes come in the 5.75 size. If your frame is cut for a shorter ANSI strike opening, the frame gets routed to suit rather than the strike being swapped.
4) My door is on butt hinges and swings one way. Do I need a double lipped strike?
No. The double lip exists to protect the frame when a center hung door swings in both directions. A conventional single-acting door on full mortise butt hinges takes a standard single-lip ANSI strike instead. Buy the DLS-1 only if the opening is center hung with a 1/8 inch inset.
5) What is the difference between the BEST DLS-1 double lipped strike and a full mortise hinge like the Ives 3CB1HW?
They do different jobs on the same opening. The DLS-1 is a double lipped strike that mounts in the frame and receives the latch bolt, with a 1-1/4 inch by 11/16 inch latch bolt cutout meeting ANSI standards for heavy duty bored type locks and .093 inch material. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, which carries the door leaf on the jamb. A center hung door needing bi-directional swing needs the strike for the latch and separate hinges or pivots for the swing; one does not replace the other.
6) Can a Don-Jo HWBB84545 be used instead of a BEST DLS-1?
No. The Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, in satin chrome. The BEST DLS-1 is a strike for 1/8 inch inset center hung doors, with a double lip that lets the door swing in both directions without frame damage. Replacing a strike calls for a strike; the Don-Jo is the hinge side of the opening.
7) Does a Stanley 2060R spring hinge give the same two-way swing as a BEST DLS-1?
They address different parts of a two-way opening. The Stanley 2060R is a full mortise spring hinge, square corner, 4.5 inch by 4.5 inch on a ferrous steel base, which controls closing at the hinge side. The BEST DLS-1 is the double lipped strike that lets a center hung door on a 1/8 inch inset pass the frame in both directions without damage, with a 5-3/4 inch cased opening. A double acting opening typically uses both: hinge or pivot hardware for the swing and the double lipped strike so the latch clears from either side.
8) Is the DLS-1 heavy enough for a hospital or school corridor door?
Material thickness is .093 inch and it is rated commercial, heavy duty, which is the range you want on patient room and classroom openings that get pushed through with carts and gurneys. The square corner profile matches standard commercial frame prep.
9) What finishes does the BEST DLS-1 strike come in, and can I match the rest of my door hardware?
Three finishes: 605 bright brass, 612 satin bronze, and 626 satin chrome. Those are BHMA finish numbers, so a 626 strike lines up with the 626 lever and closer already on the opening. If you are standardizing a building on satin chrome, 626 is the one to hold on the shelf.
10) Does the DLS-1 strike replace the hinges on a center hung door?
It does not. The DLS-1 handles the latch side only. A center hung door still needs its pivot set or hinges specified separately, and if the opening is actually a conventional mortised frame you would be looking at full mortise butt hinges such as the Ives 3CB1HW heavy weight concealed bearing hinge or the Hager BB1168 with non-removable pin.
11) The door needs to swing both ways and carry electrified hardware. What works with the DLS-1?
The DLS-1 handles the latch side, allowing a center hung door on a 1/8 inch inset to open in both directions without frame damage. For power to the door leaf, Command Access energy transfer hinges carry the wiring: the ETH-BB68 is a 5 knuckle heavy duty steel base hinge in the ETH 5 Series, and the ETH-CB70 is a 3 knuckle standard weight in the ETH 3 Series at medium duty. If door position also needs monitoring, the ETM-BB68 adds an integrated door position switch and the ETM-CB70 adds door position sensing on a 3 knuckle steel base.
12) For a heavy traffic commercial opening, what heavy duty hinges pair with a BEST DLS-1 strike?
The DLS-1 is rated heavy duty for commercial use, so the hinges on the same opening should match. Heavy duty options include the Don-Jo HWBB75045 heavy weight full mortise ball bearing hinge at 5 inch by 4-1/2 inch, the Hager BB1168 non-removable pin full mortise ball bearing hinge, and the Ives 3CB1HW concealed bearing full mortise hinge. Medium duty hinges such as the Ives 3CB1 or the Orca 4040 Series 4 inch by 4 inch square corner plain bearing hinge sit at a lower duty rating.
13) Is the BEST DLS-1 a residential part, or does it need commercial grade hardware around it?
The DLS-1 is a commercial, heavy duty part with square corners and a .093 inch material thickness. Residential duty companions such as the Emtek 91013 residential plain bearing hinges in 3-1/2 inch by 3-1/2 inch square corner plated steel, the Delaney 3-1/2 inch by 3-1/2 inch bulk steel residential interior hinges with a 5/8 inch radius, or the Deltana DSB35 3-1/2 inch square residential hinges are built for a different service level. On a commercial opening the surrounding hardware is usually specified to match, for example the Delaney CH401X 4 inch by 4 inch commercial ball bearing hinge with square corners.
14) The opening is square corner prepped. Which hinges match that prep alongside a DLS-1 strike?
The DLS-1 uses square corner styling. Square corner hinges that match that prep include the Delaney CH401X 4 inch by 4 inch commercial ball bearing hinge, the Orca 3535 Series 4-1/2 inch by 4-1/2 inch ball bearing commercial hinge, the Orca 4040 Series 4 inch by 4 inch plain bearing hinge, the Deltana CSB45N 4-1/2 inch square hinge with non-removable pin, and the Stanley 2060R spring hinge, full mortise square corner in 4.5 inch by 4.5 inch ferrous steel base. Radius corner options such as the Orca 4014 Series 4 inch by 4 inch with a 1/4 inch radius or the Delaney 4 inch exterior residential hinges with a 5/8 inch radius need a different frame prep.
15) What matches a BEST DLS-1 in satin chrome across the rest of the opening?
The DLS-1 comes in 605 bright brass, 612 satin bronze, and 626 satin chrome, all in the 5.75 size. For a satin chrome opening, the Don-Jo HWBB74545 heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch, the Don-Jo HWBB75045 at 5 inch by 4-1/2 inch, and the Don-Jo HWBB85045 brass hinge at 5 inch by 4-1/2 inch are all supplied in satin chrome.
16) For a detention or high security door, is the BEST DLS-1 the right strike?
The DLS-1 is built for commercial heavy duty service on 1/8 inch inset center hung doors that swing both ways, and its cutout is sized for heavy duty bored type locks per ANSI. Detention openings are typically built around hinges made for that use, such as the Hager 990 full surface prison hinge at 3 inch by 4 inch with a welded tip in heavy duty, or the Stanley BB855 double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged. Security hinge options for lighter work include the Deltana DE44R5TA 4 inch by 4 inch security hinge with a 5/8 inch radius in steel.
17) What frame prep does installing a BEST DLS-1 involve?
Route the frame for the 1-1/4 x 11/16 inch latch bolt cutout, drill the mounting holes off the manufacturer template, fasten the strike, then set its position so the latch engages cleanly with the door swinging both directions and neither lip contacts the door edge on the return swing. Alignment is the step people rush; on a bi-directional opening a strike that is proud on one side will drag every cycle.
18) Will a McKinney MP79 or MPB79 work on the same opening as a BEST DLS-1?
The McKinney MP79 MacPro full mortise hinge and the MPB79 MacPro hinge are both 5 knuckle standard weight and carry a standard duty rating. The DLS-1 strike is specified heavy duty commercial with .093 inch material, so on an opening being built to a heavy duty spec the hinges are usually chosen at the same level, such as the Stanley FBB191 5-knuckle full mortise hinge in 4.5 inch by 4.5 inch or the Don-Jo HWBB84545 heavy weight ball bearing hinge.
19) Is the McKinney SQ3331 an alternative to the BEST DLS-1 for a square corner opening?
No. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge in 4-1/2 inch by 4-1/2 inch at standard duty, chosen for appearance at the hinge side. The BEST DLS-1 is the strike that receives the latch bolt on a 1/8 inch inset center hung door, with square corner styling and a 5-3/4 inch cased opening. Square corners are shared styling, not interchangeable function.
20) Does the DLS-1 come in a non-ferrous version for a corrosive environment?
The DLS-1 is offered in 605 bright brass, 612 satin bronze, and 626 satin chrome. Where the hinge side needs a non-ferrous base, the McKinney T2314 is a non ferrous hinge in standard weight with 5 knuckles at medium duty, and the Don-Jo HWBB85045 is a brass heavy weight ball bearing hinge in 5 inch by 4-1/2 inch. Steel base hinges such as the Emtek 92013 heavy duty plain bearing hinges in plated steel use a ferrous base.
