The Tenn-Tex C-683 is a left-hand rear mounting bracket designed to support the back end of an undermount drawer slide in face-frame and deep-cabinet installations where the slide needs an extended rear anchor point. With a 76mm extension reach and a 10mm dowel mount, this bracket seats into a bored hole at the rear of the cabinet and holds the slide level at the correct elevation — no rear wall drilling required where the geometry fits a dowel-locating setup. Sold 25 per box.
Rear mounting brackets exist because undermount slides need support at both ends. The front of the slide is handled by the locking device under the drawer box; the rear end needs a solid anchor to the cabinet body. In face-frame cabinets, the rear panel sits well behind the frame, so the slide's back end is often left hanging without a dedicated bracket. The C-683's 76mm extension arm reaches that rear position and gives the slide a stable footing — critical for keeping the drawer running straight through years of use.
The 76mm reach is longer than the standard short-arm rear brackets in this family, which makes the C-683 the right choice when the slide's rear socket falls farther from the cabinet back than a shorter bracket can span. If your layout puts the slide's rear anchor point close to the back wall, a shorter bracket from the same program may be the better fit.
The bracket mounts by dowel: the 10mm post seats into a 10mm hole bored at the bracket's intended rear location. Dowel mounting locates the bracket precisely and consistently across a run of cabinets, which matters when you are installing a batch and need every rear bracket at the same elevation. The 6mm fitment dimension interfaces with the slide's rear socket — confirm this dimension against your slide specification before ordering, because rear brackets are not interchangeable across slide series or brands.
This is a Tenn-Tex component. Use it with the slide series it was engineered for; rear brackets from other programs will not seat or align correctly even if the dowel diameter matches.
Cabinet shops running face-frame production will go through rear mounting brackets at roughly one pair per drawer. The 25-count box suits a smaller run or a shop that stocks several bracket sizes and does not want to overcommit to one. Contractors retrofitting undermount slides into existing face-frame cabinetry will find the extended 76mm arm particularly useful where the original cabinet construction left little room for a short-arm bracket to land cleanly. This bracket is also a logical reorder when a job calls specifically for the left-hand C-683 and the right-hand C-683-01 has already been sourced separately.
You need one bracket per slide — one left-hand C-683 and one right-hand C-683-01. The two together anchor both rear ends of the slide pair. This box contains 25 left-hand brackets; order the matching right-hand box separately.
The 6mm is the bracket's fitment dimension — the measurement that must match the rear socket specification of the slide you are installing. Confirm this against the slide's installation spec before ordering; a bracket with the wrong fitment dimension will not seat the slide at the correct height or angle.
The 76mm arm is for layouts where the slide's rear anchor point falls farther from the back panel than a standard-reach bracket can span. Face-frame cabinets with deep setbacks and thick rear blocking are typical situations. If your slide seats close to the back wall, check whether a shorter bracket from the C-419 or C-283 series fits your geometry.
No. Rear mounting brackets are engineered to specific slide series; the fitment dimension, socket geometry, and dowel position are all matched within one program. This bracket is a Tenn-Tex component and should be used with the Tenn-Tex slide series it was designed for.
A rear mounting bracket is a small part with a large effect — skipping it or using the wrong one puts the entire slide's alignment at risk. The C-683 gives the left side of a deep-layout undermount installation a solid, precisely located rear anchor, so the slide runs true from the first pull and keeps running that way.
