NGP 159MDKB – Frequently Asked Questions

1) Is the NGP 159MDKB magnetic seal long enough for a standard 7-foot door, and can I get it longer?
The 159MDKB comes pre-cut at 84 inches, which covers the full height of a standard 7-foot door leaf on the hinge or strike jamb. If you have taller openings, the magnetic seal is available in lengths up to 144 inches, so a single piece can run a 10-foot jamb without a splice.
2) How does a magnetic door seal differ from a standard vinyl or silicone compression gasket?
A compression gasket seals only when the door squeezes it shut, so the seal quality depends on how tightly the door is hung. The NGP 159MDKB works differently: a magnet encased in gray vinyl pulls itself against the door face to hold consistent contact, which is why it is used where weatherproofing and sound control both matter. It does require a steel door or frame for the magnet to grab. If you have an aluminum or wood opening, a mechanical compression gasket like the Cal-Royal PG-601 aluminum channel perimeter gasketing with vinyl insert is the type to use instead.
3) Do I need two of these to seal one door, or three?
The 159MDKB is an 84 inch piece for one vertical jamb. A full perimeter seal on a single door takes two verticals plus a head piece cut from the same material, and the seal is offered up to 144 inches, so one long piece can be cut down to cover the head. It does not seal the bottom of the door: that needs a door bottom or sweep.
4) What is the difference between the NGP 159MDKB magnetic seal and Cal-Royal PG-601 perimeter gasketing?
Both are aluminum-channel perimeter seals applied to the door frame stop, but they seal by different means. The NGP 159MDKB uses a gray vinyl-encased magnet that pulls against the door face for contact, in aluminum alloy 6063 T5 temper with a dark bronze finish and slotted screw holes for adjustment after mounting. The Cal-Royal PG-601 is an aluminum channel carrying a vinyl insert, so the seal is made by compression of the vinyl bulb against the door rather than by magnetic attraction. The magnetic approach requires a steel door or steel-faced door for the magnet to grip; a vinyl-insert channel like the PG-601 works against wood and aluminum doors as well.
5) I need perimeter gasketing for a wood door - can I use the NGP 159MDKB?
The 159MDKB seals with a vinyl-encased magnet, which depends on a ferrous door face to hold contact, so it is not the right choice for a wood or aluminum door leaf. For those openings, a compression-style channel such as the Cal-Royal PG-601, an aluminum channel with a vinyl insert, seals by bulb compression against the door regardless of what the door is made of.
6) Can the NGP magnetic seal be adjusted after it is screwed to the frame?
Yes. The retainer has slotted screw holes, so you can set the seal, check the contact along the door face, and shift it in or out before final tightening. Fasteners are included: #6 x 3/4 inch stainless steel sheet metal screws.
7) Will this magnetic seal hold up on an exterior door in cold or hot weather?
The seal is rated for service from 0 F to 140 F, and the vinyl is a PVC formulation made with a bio-based plasticizer that resists flame and moisture. The retainer is aluminum alloy 6063 in T5 temper, which resists corrosion on exterior openings. Below 0 F is outside the stated range.
8) Is the Cal-Royal PG-601 a direct replacement for an NGP 159MDKB magnetic seal?
It is a functional alternative rather than a like-for-like swap. The PG-601 is an aluminum channel with a vinyl insert and does not carry a magnet, so the sealing action and the adjustment method differ from the 159MDKB, which uses slotted screw holes to fine-tune magnet contact after the strip is mounted. The 159MDKB also ships pre-cut to 84 inches in dark bronze with #6 x 3/4 inch stainless steel sheet metal screws, so if you are matching existing bronze head and jamb strips on other openings, staying with the NGP seal keeps the finish and the hardware consistent.
9) Is the dark bronze finish the only option on the NGP 159MDKB?
The 159MDKB part number is the dark bronze version, and dark bronze is the only finish carried under that number. It is meant to blend with bronze-anodized frames and dark commercial door hardware. If your openings are mill aluminum or painted, order the corresponding finish variant of the magnetic seal rather than this one.
10) Is this magnetic seal suited to commercial buildings or light residential use?
It is a commercial-duty product, used on office buildings, schools, healthcare facilities, retail, industrial and warehouse space, multi-tenant residential and government buildings. The aluminum 6063 T5 retainer and stainless fasteners are chosen for traffic and exposure that light residential weatherstripping would not take.
