A single-needle drop feed machine arrives with one foot: the flat one bolted on at the factory. It sews a plain seam and nothing else. It cannot hold a zipper tape at a fixed distance, keep a topstitch parallel to an edge, or move coated vinyl that grabs the steel. Those are different feet.
Which presser feet fit your machine?
The answer is not the brand on the head. It is the shank. Industrial single-needle lockstitch machines use a standard low-shank attachment, and a foot cut for that mount fits any machine that has it, whoever built the machine. That is why a single foot listing covers Juki, Jack, Siruba, Speedway, Brother and Zoje in the same breath.
The Juki DDL-8700 is the machine the class is usually named after, so "DDL-8700 compatible" has become shorthand for the standard low-shank single-needle drop feed bench. Check your own machine's shank before ordering: most benches in this class take these feet, but every brand has a few models that sit outside it.

Zippers take two feet, not one
A zipper foot is cut away on one side so the needle rides right against the teeth. That cutaway has a handedness, which is why the P36N right-hand foot exists alongside a left-hand pair.
Buying only one and reaching the second side by turning the work is how seams end up crooked. The fabric approaches the needle at a different angle, the cutaway sits on the wrong side of the coil, and the stitch line drifts away from the tape. Both feet handle coil, invisible and metal-tooth zippers, so the pair covers every zipper a garment, bag or cushion will ever need.
How do you keep a topstitch parallel to the edge?
Two feet solve this, and they solve it differently.
The CLI-16N edge compensating foot has a spring-loaded half that rides against the fabric edge. The sole does the tracking, so the topstitch stays parallel without the operator watching the edge instead of the needle. It follows a curve as well as a straight run, which is the part an edge guide bolted to the bed cannot do.
The TCR-1/4 takes the opposite approach: the sole itself is a quarter inch from needle to edge, so there is nothing to set and nothing to drift. Use it when every seam on the job is the same allowance. Use the compensating foot when the allowance changes, or when the edge does.
What moves vinyl and leather that drags?
Coated vinyl, laminates and finished leather stick to a steel sole. The material stalls under the foot while the feed dog keeps pulling from below, and the result is a short stitch, a skipped one, or a scuff across the face.
A roller foot such as the JK-P351 replaces the flat sole with a wheel that rolls over the surface instead of sliding across it. The rubber three-wheel version goes further: three rubber wheels add grip on top of the rolling action, for material that still slips under a single steel roller. Reach for the plain roller first, since it marks less.
Delicate faces, tight corners and gathers
Three more feet cover the jobs a steel sole handles badly.
- The MT-18 plastic flat foot will not leave a shine on satin, coated cloth or anything with a pressed finish. Same shape as the standard foot, different material.
- The toothpick foot has a narrow sole that enters corners and channels a standard foot is simply too wide to reach.
- The P952 gathering foot makes the fabric gather as it sews. The thumbscrew sets spring pressure on a hinged sole, so the feed dog pulls the bottom layer faster than the top. Tighten for a close ruffle, back it off for a soft one. Skirts, curtains, cuffs and yokes without basting by hand first.
The mistake we correct most often
The P952 is sold under several names, usually "adjustable" and sometimes "compensating". It is neither. There is no guide and no fence anywhere on it, so it cannot set a seam allowance, and it does not track a fabric edge. The thumbscrew adjusts pressure, not distance.
If you want a consistent seam allowance, that is the CLI-16N or the TCR-1/4. If you want an edge tracked around a curve, that is the CLI-16N. The P952 does one thing and does it well: it gathers.
The two tools that are not feet
Neither of these mounts to the machine, and both change how the feet above get used.
The Jack 815165 is four tools in one small plate. It magnets to the bed and becomes a seam guide, with a straight edge for straight runs and a rounded end for curves. A rule runs down both edges for setting allowance, a lens reads a stitch too small to see by eye, and a steel hook threads the needle in one motion.
The Jack 814459 foot change device holds the foot in place while you work the screw, so it does not drop into the bed and disappear. That is the difference between a foot change taking ten seconds and taking two minutes, which in turn is the difference between swapping to the right foot and making do with the wrong one.
Quick reference
Nine feet and two tools, by job
| Part | Job | Reach for it when |
|---|---|---|
| P36N and left-hand pair | Zippers | The needle has to sit against the teeth, from either side |
| CLI-16N | Parallel topstitch | The allowance changes, or the edge curves |
| TCR-1/4 | Fixed quarter-inch seam | Every seam on the job is the same allowance |
| JK-P351 roller | Vinyl, leather, laminates | The material sticks to a steel sole and stalls |
| Rubber 3-wheel | Grip beyond a roller | A single steel roller still slips |
| MT-18 plastic | Delicate faces | Steel would leave a shine on satin or coated cloth |
| Toothpick foot | Corners and channels | A standard sole is too wide to enter |
| P952 | Gathers and ruffles | You want fullness sewn in, not basted by hand |
| Jack 815165 | Guide, rule, lens, threader | Always. It lives on the bed |
| Jack 814459 | Changing feet | You own more than one foot |
