BAL 29015B
Sidewind A-frame jack · 1,000 lb
1,000-lb side-crank model; 14-in extension range. Uses the smaller 1⅝-in inner jack leg.
BAL A-Frame Trailer Tongue Jacks: Wind Style, Feet & Casters
Two trailer tongue jacks can have the same 14-inch travel yet use different crank positions, tube diameters and load ratings. This BAL model guide compares five manual A-frame jacks, then separates compatible feet and casters by lower-leg size. Use the part number on the existing jack and the trailer's actual tongue weight to choose the correct assembly.
Choose by crank location, rating and tube size
Sidewind or topwind?A sidewind crank operates from the side of the jack. Topwind models operate from above. Check clearance around the coupler, front storage box and propane bottles before choosing.
Match the rated loadBAL offers 1,000-, 2,000- and 5,000-lb jack versions in this group. Compare the trailer's real tongue weight and mounting arrangement rather than matching travel alone.
Check the lower legThe 1,000-lb 29015/29020 models use a 1⅝-inch inner leg. The 29025/29030/29033 range uses a 2-inch inner leg, requiring different pinned-on accessories.
Wheel-capacity warning: The 29041B caster fits certain 2,000- and 5,000-lb jacks but the caster itself is rated for 1,000 lb. Installing it does not give the caster the jack's higher rating. The lowest-rated component governs the supported load.
BAL A-frame tongue jack MPN and travel chart
These five manual jacks are retail-boxed “B” models. All have 14 inches of extension travel, but the cranking direction and tube size vary. Travel figures are for the jack's extendable tube, not a complete installed height with a caster or foot.
| MPN | Crank | Rated load | Tube travel | Inner leg | Product |
|---|---|---|---|---|---|
| 29015B | Sidewind | 1,000 lb | 7½–21½ in | 1⅝ in | View part |
| 29020B | Topwind | 1,000 lb | 7½–21½ in | 1⅝ in | View part |
| 29025B | Sidewind | 2,000 lb | 8–22 in | 2 in | View part |
| 29030B | Topwind | 2,000 lb | 8–22 in | 2 in | View part |
| 29033B | Topwind | 5,000 lb | 8–22 in | 2 in | View part |
Foot plates and casters: select the correct leg size
Smaller 1⅝-inch legs accept BAL 29050B or 29036B. For the 2-inch leg on 29025B, 29030B and 29033B, compare 29056B, 29055B or 29041B. Each accessory has its own load and dimension requirements.
| MPN | Accessory | Leg | Rating or dimensions | Product |
|---|---|---|---|---|
| 29050B | Short foot for 1⅝-in leg | 1⅝ in | Check jack rating; 4 × 8-in pad | View part |
| 29036B | 6-in swivel caster, small leg | 1⅝ in | 1,000 lb caster; 6-in wheel | View part |
| 29056B | Short foot for 2-in leg | 2 in | 5,000 lb foot; 4 × 8-in pad | View part |
| 29055B | Extended foot for 2-in leg | 2 in | 5,000 lb foot; 7-in height addition | View part |
| 29041B | 6-in swivel caster, large leg | 2 in | 1,000 lb caster; 6-in wheel | View part |
The short 29056B foot adds approximately half an inch of height; the 29055B extended foot adds about seven inches. Both have a 4 × 8-inch base and are for the larger two-inch leg. Verify the retaining-pin hole and foot clearance on the actual jack.

Common tongue jack replacement questions
Can I use a 2-inch jack caster on a 1⅝-inch lower leg?
No. The 29041B is intended for the two-inch leg, whereas 29036B is the caster for the smaller BAL 1⅝-inch leg. Match the tube dimensions and retaining-pin position.
Does a 5,000-lb jack automatically support a 5,000-lb caster load?
No. The 29041B caster is rated for only 1,000 lb, even on a compatible 5,000-lb jack. Always apply the lowest component rating.
What distinguishes 29015B from 29020B?
Both are 1,000-lb manual A-frame jacks with 14 inches of tube travel. 29015B is sidewind and 29020B is topwind, with different main housing lengths. Check crank clearance and the existing mounting.
Are 29055B and 29056B interchangeable?
They suit the same larger-leg jack family but differ substantially in foot height. Choose according to ground clearance, extension requirements and the installed retaining-pin position.
