A folding shelf that drops unexpectedly, or a table leaf that refuses to release, may not need the same replacement hardware. JR Products uses different bracket sizes for fold-down shelves and separate spring-loaded Saf-T-Ring supports for table leaves. RV Designer also has a paired folding bracket set. Compare the original hardware and supporting surface before deciding.

Identify the original shelf or table support

JR's published 50 lb rating applies to its folding shelf bracket models when properly installed. The table-leaf supports and RV Designer H505 are different mechanisms; no matching load rating is established for those items here.

MPN Component Published dimensions Published support rating Brand
20725 White folding shelf bracket 12 × 12 × 16½ in 50 lb JR Products
20735 Brown folding shelf bracket 7¾ × 7¾ × 11¾ in 50 lb JR Products
20755 Six-inch table-leaf support 6 in — JR Products
20765 Twelve-inch table-leaf support 12 in — JR Products
H505 Folding shelf brackets, pair 8 × 8 in — RV Designer
Check how the support releases. JR Products 20755 and 20765 are spring-loaded drop-leaf table arms with a Saf-T-Ring release. The 20725 and 20735 are folding shelf brackets in different sizes. RV Designer H505 supplies a pair of 8 × 8-inch folding brackets; its 8-inch measurement is not a verified load rating.

What to compare on the original part

  1. Identify a folding shelf versus a drop leaf: a folding triangular support is not the same as a spring-loaded table-leaf arm.
  2. Measure all sides: the white JR 20725 is listed as 12 × 12 × 16½ inches; the brown 20735 as 7¾ × 7¾ × 11¾ inches.
  3. Check the release: JR 20755 is a 6-inch Saf-T-Ring leaf support, while 20765 is 12 inches.
  4. Count the supplied brackets: RV Designer H505 is a pair of brown 8 × 8-inch folding brackets. The JR bracket's listed rating must not be applied to it.
  5. Inspect the mounting: weakened thin cabinet walls, missing fasteners and damaged hinges can make even a correct bracket unsafe.
