Rack Shelf Kits – the CASA modular CKD answer to versatile 19” Rack mounting of non-standard equipments.

 

 

We have started a small pilot-production batch of these in 1U & 2U x 300mm deep.

The general format if represented in this DRAFT drawing of a 2U x 300 shelf-kit

The range embraces sizes from 1U x 150mm deep to 6U x 400mm deep, however, greater depths can be produced against firm orders.

 

The 5 proposed standard bottom/base panel front/rear fold options are represented in this PDF:

Introduction:

 

Our 1-piece-shelves are economic in production but require significant set-up time and 50+ batches to achieve economics in pricing. We're prompted to offer the CKD MODULAR version now being prototyped from an initial design just completed and represented in the above 3D drawing (left-hand side exploded and bottom panel with FURU folds installed in the standard mode).

Features & Advantages Include:

a) CKD kitset design offers extended modularity variants without the high batch numbers required to achieve economy in our one-piece design while still conforming to appropriate standards.

b) Additional shelf-trays can be added to provide lids or intermediate shelves in a single shelf-chassis.

c) Shelf-base-plate (tray/trays) can be installed inverted and/or readily supplied with front/rear folds (up-or-down) to meet specific needs

 

d) Vertical internal panels may be mounted behind the rack-fixing face as a substitute to base/bottom panels or in addition to the base/top/panels etc. – we welcome discussion about specific needs.

e) Lacing bars (M4 as used on CASA patch-panels or M5 for additional strength) can be fitted to support incoming cables

f) A shelf-tray with mounting for axial fans (to make a forced-air- cooler for rack-equipments) is proposed for stock availability. Fans may also be included in custom side-brackets.

g) The independent tray/base and sides makes for easier customizing by installer or CASA

h) When ordered with pre-fitted M5 PEM self-clinching studs into the appropriate side-bracket holes, user's assembly is facilitated by just fitting 4~6 x M5 hex nuts (with or without spring-washers).

i) Many of the special accessories designed for the original CASA one-piece-shelves are applicable to the CKD shelf-modules including the rear-support (high-load) gusset plates.

j) The present 4U height limit (of the one-piece-folded-shelf) is eliminated (we can't fold a 1-piece-shelf greater than 4U high) and can be economically addressed with additional (5U and 6U) side-brackets (yet to be introduced into stock).

k) Custom modifications/machining can be more readily achieved on the separate parts (fully-folded shelves are cumbersome to re-work in the drill press or stamping press etc.)

 

l) Packing and handling in CKD form is less bulky and less expensive

Disadvantages:

1) there is a small internal size compromise introduced by the side flanges and M5 fasteners on the shelf-base (tray) and if/when the tray is mounted inverted (14mm side-flanges downward) a 14mm loss of internal height.

2) if conventional fasteners are used on the side-brackets in place of (or additional too) the PEM Flush-Studs some care is required to ensure adequate side-clearance to the rack frame in which the shelves are to be installed. Pre-installation of the M5x0mm PEM flush-head studs requires the rack-brackets to be supplied in LH and RH matching pairs.

3) the CKD modularity/flexibility/versatility costs slightly more than the one-piece-shelf

Progress Delivery and Prices:

An initial selection of IU and 2U x 300mm blanks are already produced and ready for finishing (selected options are being paint/electroplate and assembled for samples for photographing etc.)

A quotation-template is offered as a guide to your prospective interests. A typical representative one-piece-shelf is included/priced for comparison (this RS-2Ux300 one-piece-shelf is based upon a minimum factory order of 50).

These draft prices are indicative and as expected, more expensive than the 1 part folded version. Further pricing will be available/updated when we have confirmed production costs based upon the prototypes/samples AND a good batch-size is determined - PERHAPS - with some customer orders?

Comments & Criticisms:

Your comments will be appreciated relative to your expected uses or future applications.
