Trine 4100RX-250-US32D – Frequently Asked Questions
1) What does the Trine 4100RX-250 ramp extension actually do on a 4100 Series electric strike install?
It is a stainless steel ramp extension that adds 1/4 inch of ramp to a Trine 4100 Series electric strike, so the latchbolt rides in and seats cleanly when the door and frame are not perfectly aligned. It doubles as a trim skirt, covering the cut-line pocket left in the jamb so the finished opening does not show the prep. It is an accessory, not a strike: the 4100 Series strike body is a separate part and this does nothing on its own.
2) Will the Trine 4100RX-250 ramp extension work on a Timely or Redi knock-down frame?
Yes. The 1/4 inch ramp extension is called out for Timely, Redi, Raco and IDP frames and similar hollow metal frames, which is exactly where the strike ramp tends to sit short of the latch and where the pocket cut shows. It only fits Trine 4100 Series strikes; it is not a universal ramp for other brands' strike bodies.
3) My electric strike latch is not catching consistently on a hollow metal frame. Does adding a ramp extension fix that, or do I have the wrong strike?
If the latchbolt is glancing off or dragging on the ramp because the door sits slightly proud of the jamb, the Trine 4100RX-250 adds 1/4 inch of ramp to a 4100 Series strike and pulls the latch into the keeper. What it will not fix is a lock the strike was never meant to take. The 4100 Series works with mortise or cylindrical locks, so if you are on a rim exit device or a surface vertical rod, you need a different strike entirely, such as the SDC 30-4 Series rim mount strike for a 3/4 inch Pullman latchbolt or the HES Folger Adam 310-4-2 pac for surface vertical rods.
4) The strike is going on an exterior gate. Is the Trine 4100RX-250 the right accessory there?
No. The 4100RX-250 is not outdoor rated and is meant for interior commercial frame installations on Trine 4100 Series strikes. For an exterior gate, the Camden CX-ED1959 Series is an outdoor rated electric gate strike. Specify the outdoor rated strike for the gate and keep the ramp extension for the interior 4100 Series openings.
5) Is the Trine 4100RX-250 ramp extension a replacement for an electric strike, or does it only work with one?
The 4100RX-250 is not a strike. It is a 1/4 inch stainless steel ramp extension made to finish a Trine 4100 Series electric strike installation, improving latch entry and alignment and acting as a trim skirt over the cut-line pocket. If you need the strike itself for a cylindrical or mortise lock opening, that is a different part: the Von Duprin 6400 32D is a Grade 1 modular fail-secure electric strike for mortise or cylindrical locks in satin stainless steel, and the Hager 2930 is a fire rated Grade 1 electric strike for cylindrical and mortise locks with 12/24VDC dual voltage. Order the ramp extension in addition to a strike, not instead of one.
6) The frame pocket is cut too large and the strike looks unfinished. What are my options besides a ramp extension?
One route is the Trine 4100RX-250, a 1/4 inch stainless steel ramp extension that doubles as a trim skirt to help conceal the cut-line pocket on a Trine 4100 Series strike. The other route is a strike that ships with its own faceplate coverage instead: the Camden CX-ED1689L-4 is a fire rated universal low profile strike supplied with four faceplates, and the Camden CX-ED1799L-8 is a fire rated dual monitor Grade 1 strike supplied with eight faceplates. Multiple faceplates let you pick the plate that covers the existing prep; the ramp extension addresses the pocket on an existing 4100 Series installation without changing the strike.
7) I am working an aluminum storefront jamb, not a Timely or Redi hollow metal frame. Does the 4100RX-250 apply?
The 4100RX-250 ramp extension is intended for Timely, Redi, Raco, IDP and similar hollow metal frames on Trine 4100 Series strikes. For aluminum jambs the strike selection itself changes: the Adams Rite 7100 Series is an electric strike for aluminum jambs with a flat faceplate measuring 1-1/4 inch by 4-7/8 inch, and the Adams Rite 7160 is an electric strike for aluminum jambs with a 1-1/4 inch by 4-7/8 inch faceplate. Both are non fire rated. If the jamb is hollow metal or wood instead, the Adams Rite 7170 covers that with the same 1-1/4 inch by 4-7/8 inch faceplate.
8) Can I avoid cutting the frame instead of adding a ramp extension to cover the cut?
Yes, that is a different strategy for the same problem. The Trine 4100RX-250 is a finishing part: it extends the ramp 1/4 inch and skirts the cut-line pocket after a 4100 Series strike is installed. The Locknetics NC450 US32D is a no cut electric strike, which addresses the frame appearance by not requiring the cut in the first place. Choose the no cut strike when the frame is still untouched; choose the ramp extension when a 4100 Series strike is already in and the pocket needs covering.
9) The opening is fire rated. Does the Trine 4100RX-250 suit it, and which strikes go with it?
The 4100RX-250 carries a fire rating designation and is for commercial mortise or cylindrical lock openings at 12/24 VAC/DC. Fire rated strike peers include the Von Duprin 6210 for mortise locks, 24 VDC fail-secure and UL 10C fire rated; the Von Duprin 4211 32D for cylindrical locks, 12/24 VDC field-selectable, Grade 1 heavy duty; and the Camden CX-ED1410 and CX-ED1420 universal Grade 1 ANSI fire-rated strikes. The Adams Rite 7100, 7160 and 7170 are not fire rated, so they are the ones to rule out on a rated opening.
10) My opening is a pair of doors with surface vertical rods, not a cylindrical or mortise latch. What do I order instead?
The 4100RX-250 ramp extension belongs to a mortise or cylindrical lock application. For surface vertical rod exit devices, the HES Folger Adam 310-4-2 is a complete electric strike pac for surface vertical rods, Grade 1. For a double door with a 3/4 inch keeper, the Rockwood ESK-DBL is a fire rated Grade 1 double door electric strike in the 310-1 Series. For a rim exit device, the Hager 2945 is a fire rated rim exit strike with field selectable fail safe/fail secure and a latchbolt monitor.
11) The real problem is that the latchbolt is not seating in the keeper. Is a ramp extension the fix, or should I change strikes?
The Trine 4100RX-250 adds 1/4 inch of ramp to improve latch engagement and door alignment on a Trine 4100 Series strike, which addresses a marginal entry angle on an existing installation. If the mismatch is latchbolt throw rather than alignment, the strike is the part to change: the HES Folger Adam 310-1(X) strike body accepts 1/2 inch, 5/8 inch or 3/4 inch throw latchbolts, the SDC 15 Series takes a 5/8 inch latchbolt at 12/24 VDC, the SDC 25 Series takes a 1/2 inch latchbolt, and the SDC 30-4 Series takes a 3/4 inch Pullman latchbolt in a rim mount stainless steel body. Measure the throw before deciding.
12) What finishes does the Trine 4100RX-250 ramp extension come in, and how do I match it to the strike faceplate?
Five finishes: 630 satin stainless steel, 629 bright stainless steel, 605 bright brass, dark bronze, and black powder coated. Because the ramp extension sits on the face of the jamb next to the strike faceplate, order it in the same finish as the 4100 Series strike you are installing. 630 satin stainless is the usual match on commercial hollow metal openings.
13) I standardize on HES or Von Duprin strikes across my buildings. Can I use the Trine ramp extension on those?
No. The 4100RX-250 ramp is cut for Trine 4100 Series frame preps and only fits that series. If you are standardized on another brand, get that brand's own accessory: HES publishes accessory kits for the 1500 and 1600 Series, and for a Grade 1 modular strike that takes mortise or cylindrical locks the Von Duprin 6400 is the equivalent body to spec. Mixing a ramp from one maker onto another maker's strike does not line up.
14) Are HES 1500 and HES 1600 accessories interchangeable with the Trine 4100RX-250?
No. Each accessory is keyed to its own strike family. The 4100RX-250 ramp extension is built for the Trine 4100 Series and its standard frame preps. HES 1500 Electric Strike Accessories are for the HES 1500 Series, and HES 1600 Electric Strike Accessories are for the HES 1600 Series, both Grade 1 fire rated families. Match the accessory to the strike series already in the frame rather than by appearance.
15) I need latchbolt monitoring on the opening. Does adding the Trine 4100RX-250 give me that?
No. The 4100RX-250 is a stainless steel ramp extension and trim skirt; monitoring is a function of the strike. The Dortronics 3300 Series is an electric strike with a latch bolt sensing switch at 12/24VDC and a strike plate for ANSI prep measuring 4-7/8 inch by 1-1/4 inch. The Camden CX-ED1799L-8 is a fire rated dual monitor Grade 1 strike, and the Hager 2945 includes a latchbolt monitor. Specify one of those if the access control system needs door position or latch status back.
16) Can I get the 4100RX-250 to match a bright brass or dark bronze frame, and what if I need a heavy duty strike in satin stainless?
The 4100RX-250 ramp extension comes in black powder coated, dark bronze, 605 bright brass, 630 satin stainless steel and 629 bright stainless steel, so it can be brought close to the surrounding frame trim. On the strike side, heavy duty options in satin stainless include the Locknetics MDS100 US32D and the Locknetics MS100 US32D, both heavy duty, the Locknetics CS450-32D, and the Von Duprin 6400 32D Grade 1 modular strike in satin stainless steel.
17) For a facility standardizing on Grade 1 strikes, does the Trine 4100RX-250 fit that program?
The 4100RX-250 is a commercial ramp extension accessory for Trine 4100 Series strikes and does not itself carry a grade; the grade lives with the strike you standardize on. Grade 1 options across the set include the Alarm Controls AES-100 heavy duty, the Von Duprin 4211 32D for cylindrical locks and the Von Duprin 6210 for mortise locks, both heavy duty and fire rated, the Securitron MUNL mortise unlatch strike, fire rated, and the HES Folger Adam 310-1(X) strike body. Standardize the strike first, then add the ramp extension only on the 4100 Series openings that need it.
18) The latch entry on my frame is offset. Is the ramp extension the answer or is there a strike built for that?
The Trine 4100RX-250 extends the ramp 1/4 inch to improve latch entry and alignment on a Trine 4100 Series strike. The RCI 15BS is an economy electric strike built specifically for special offset latch entry with fail-secure operation, so it handles the offset in the strike body rather than through an added ramp. It is not fire rated, which rules it out on a rated opening where the 4100RX-250 application is fire rated.
19) I need to be able to flip the strike between fail safe and fail secure in the field. Which products do that?
That is a strike function, separate from the 4100RX-250 ramp extension. The Hager 2925 offers field reversible fail safe/secure operation with a 5/8 inch latch, the Hager 2928 offers field reversible fail safe/secure operation, and the Hager 2930 combines field reversible fail safe/secure with a fire rating, Grade 1, and 12/24VDC dual voltage for cylindrical and mortise locks. By contrast the Von Duprin 6210 is fail-secure and the Von Duprin 6400 32D is a fail-secure modular strike.
20) Does the Trine 4100RX-250 change the voltage or wiring of the strike it goes on?
No. The 4100RX-250 is a stainless steel mechanical ramp extension and trim skirt; it adds no electrical component to the opening, and the application runs at 12/24 VAC/DC. Strikes in the same voltage neighborhood include the SDC 15 Series at 12/24 VDC, the Dortronics 3300 Series at 12/24VDC, the Von Duprin 4211 32D at 12/24 VDC field-selectable, and the Hager 2930 with 12/24VDC dual voltage. The Von Duprin 6210 runs at 24 VDC, so confirm the power supply before pairing it.
21) Is there a fire rated strike with a radius corner faceplate for a frame prepped that way, since the ramp extension covers a square cut?
The 4100RX-250 is a 1/4 inch ramp extension that skirts the cut-line pocket on a Trine 4100 Series strike installation. If the frame prep calls for a radius corner plate instead, the SDC 45F Series is a fire-rated electric strike with 5/8 inch latchbolt compatibility and a radius corner faceplate. The Dortronics 3300 Series carries a strike plate for ANSI prep at 4-7/8 inch by 1-1/4 inch if the prep is standard ANSI.
22) Does the Trine 4100RX-250 ramp extension need any wiring or power of its own?
No wiring. It is a stainless steel mechanical plate that mounts with the strike. The power goes to the 4100 Series strike itself, which runs on 12/24 VAC or VDC. Nothing about adding the ramp extension changes the voltage or the wiring at the strike.
