Design Hardware 5"x1/2" Saddle Thresholds

It's a saddle threshold 5 inches wide across the opening with a 1/2 inch overall height, extruded from 6063-TS aluminum alloy. The 1/2 inch rise is low enough to walk or roll over without a ramp, and the 5 inch width gives you room to land both the door stop line and the weatherstrip or sweep contact point on one piece.

Four stock lengths: 36, 48, 72, and 96 inches. A 36 inch piece covers a standard single door opening, 72 and 96 inch pieces cover pairs or oversized frames. Because it's extruded 6063-TS aluminum, it cuts cleanly to length with a miter saw and a non-ferrous blade, so buy the next length up and trim to your frame rebate.

Two different jobs. A 5 inch by 1/2 inch saddle is a flat-top plate you fasten to the sill, and the door bottom or sweep rides over it. The Pemko 61 Series is an interlocking J hook threshold accessory in steel construction, meant to hook into a mating door bottom hook strip for a mechanical interlock against wind-driven water. If your door already has an interlocking hook on the bottom, a plain saddle will not mate with it.

No. The Design Hardware TH5 is a saddle threshold itself - a 6063-TS extruded aluminum profile 5 inches wide and 1/2 inch high that lays across the opening and is walked on. The Pemko 61 is an interlocking J hook threshold accessory in steel construction, 36 inches long, that works with a mating hook piece rather than serving as a stand-alone saddle. If you are replacing a flat aluminum saddle under an existing door, the TH5 is the like-for-like part; the J hook is for interlocking assemblies.

Both lengths ranges come in Mill Finish and Dark Bronze. Mill finish is the bare aluminum mill surface, which matches aluminum storefront and clear anodized frames. Dark Bronze matches bronze anodized storefront, dark bronze hollow metal frames, and existing dark bronze thresholds already in a building. If you're standardizing a property, pick the one that matches the door frames you already have.

A 1/2 inch overall height is the maximum change in level allowed at a doorway under accessibility guidelines, and anything over 1/4 inch needs to be beveled. Confirm how the 1/2 inch sits relative to your finished floor on both sides before you call the opening accessible, because shimming or a raised floor covering on one side changes the effective rise.

6063-TS is the standard architectural extrusion alloy used for exterior aluminum door and window work, so it holds up outdoors. A plain saddle like this seals against a door bottom sweep or the frame weatherstrip; it has no built-in vinyl insert or thermal break of its own, so for a hard weather exposure pair it with a door sweep and set it in a bed of sealant over the sill.

Order fasteners separately. The threshold ships as the extruded aluminum saddle in the length and finish you select, and how you anchor it depends on the substrate: flat head sleeve anchors or masonry screws into a concrete sill, self-drilling screws into a steel sill pan. Countersink so the heads sit flush with the 1/2 inch walking surface.

5 inches spans the full sill on most 1-3/4 inch commercial doors with room to spare, and that extra width is what lets it cover a chipped or uneven concrete sill edge. Where the sill is shallow, a narrower saddle is the better fit, since a 5 inch plate needs the bearing surface underneath it to sit flat and not rock under traffic.

The Design Hardware 5 inch by 1/2 inch saddle threshold is extruded from 6063-TS aluminum alloy and is offered in Dark Bronze or Mill Finish, so the surface color is part of the extrusion order rather than a coating detail. The Pemko 61 interlocking J hook threshold accessory is steel construction. Aluminum extrusions are the common choice where the threshold is exposed to weather and you want the finish to match aluminum storefront trim.
