| Willach Fama 7007 Full Height Drawer System |
 |
| The lateral sections of a drawer |
| Are the lateral sections constructed with precision from a single piece of material? |
Yes |
|
| Are the lateral sections particularly strong because of their double walled structure? |
Yes |
|
| Are the surfaces of the hollow spaces electrolytically galvanised? |
Yes |
|
| Are the surfaces of the visible components natural epoxy powder coated? |
Yes |
|
| Is the height of the lateral section 80 mm, enabling a lot of smaller packs to be stacked one on top of the other without problems? |
Yes |
|
| Do the lateral sections have moulded ribs which are produced without weaknesses due to no material being removed? |
Yes |
|
| Do the lateral sections contain slots which are produced by the removal of material, thus weakening the section? |
No |
|
| Are the label-holders flush with the lateral sections? |
Yes |
|
| Do the lateral sections have deep positioned running tracks? |
Yes |
|
| Do the running tracks have specially formed guide webs which enclose both the left and right support rollers of the guiding rails? |
Yes |
| The drawer's central divider |
| Is the central divider double walled even though it is constructed from a single piece of material? |
Yes |
|
| Are the surfaces well protected with a natural epoxy powder coating? |
Yes |
|
| Does the central divider have moulded ribs which are produced without weaknesses due to no material being removed? |
Yes |
|
| Does the central divider contain slots which are produced by the removal of material, thus weakening the section? |
No |
|
| Does the central divider also support the two halves of the base so that these can measure just 3 mm in thickness? |
Yes |
| The
steel front plate |
| Does
the steel front plate have special centering grooves so that the precisely prefabricated drawer front panels can be fastened simply using centering screws? Does this mean that subsequent laborious adjustments to the front panels are not required in order to achieve a perfect alignment? |
Yes |
|
| Does the double height drawer have a single-piece frontplate? Does this mean that the drawer runs as smooth as a single height drawer, providing the same perfect alignment? |
Yes |
| Gallery rods/additional steel plate |
| Is the double height drawer supplied with a single-piece, double height steel front plate, gallery rods at the slides and an additional steel plate at the back as standard, i.e. at no extra cost? |
Yes |
| Guiding Rails |
| Is the guiding precision of the drawer also assured by specially formed guide webs which enclose the support rollers on both sides? |
Yes |
|
| Are the guiding rails powder coated instead of galvanised? |
Yes |
| Plastic sheathed steel ball bearings |
| Are all ball bearings permanently lubricated and dust-encapsulated on both sides? |
Yes |
|
| Can all ball bearings be replaced on an individual basis? |
Yes |
| The drawer bases |
What material is used in the white drawer bases?
. Very cheap hardboard, lacquered on one or both sides?
. Hardboard, PVC coated on one or both sides which easily smudges?
. Very strong MDF (medium density fibre board) which is environmentally-friendly lacquered on both sides?
|
No
No
Yes
|
|
What material is used in the transparent bases?
. Inexpensive SAN material?
. Non-scratch plexiglass with high level of transparency?
|
No
Yes |
|
What are the features of the wire-mesh base?
. Is the wire-mesh base made from expanded metal and does it have a natural epoxy powder coating, so that the minimal contact surface reduces abrasion of the packs to a minimum?
. Is the mesh, of the expanded wire-mesh metal base, positioned in the line of sight so that all packs can be easily identified, even when the drawers are overhead?
. What is the percentage of visibility allowed by the wire-mesh base?
|
Yes
Yes
73% |
| Important features for surface protection |
What surface protection is provided?
. A non-durable lacquered finish?
. A powder coating that offers a perfect edge covering and is resistant to wear?
. Polyester powder coating?
. Mixed powder coating (polyester and epoxy)?
. Natural epoxy powder coating for easy-clean surfaces?

|
| The factors that enhance a drawer's strength and bearing capacity |
| Is extra material used at the top, bottom and sides of the lateral sections, making them particularly strong? |
Yes |
|
| Are the guiding rails reinforced by means of a grooved profile? |
Yes |
|
| Are there three uprights or vertical supports which secure and stabilize the guiding rails? |
Yes |
|
| Can the drawer be pulled out and pushed in with the minimum of effort thanks to its great stability? |
Yes |
|
| Does the automatic return function come into action very quickly because there is almost no deformation of the fully extended drawer even when loaded? |
Yes |
| Points to be noted when comparing guiding precision |
| Is the drawer's guiding precision achieved through the perfect interplay between guiding rails with support rollers and drawers with laterally incorporated running tracks? |
Yes |
|
| Does the drawer require distance bracers which reduce the usable height? |
No |
|
| Does the way in which the support rollers are enclosed on both sides mean that the closed drawers maintain the necessary distance between the uprights instead of distance bracers being required? |
Yes |
|
| Are the front panels of the closed drawers in perfect alignment if the furnishing contractor has produced the panels precisely? |
Yes |
|
| Is the guiding precision of the drawer enhanced by a single-piece lateral section? |
Yes |
| Factors which influence the running action |
| Does the drawer glide open and closed with a light, precise movement so that it is impossible for it to jam? |
Yes |
|
| Do all steel ball bearings have a steel outer ring with an additional plastic sheathing, ensuring smooth running? |
No |
|
| Do all the plastic-sheathed ball bearings run exclusively on powder coating instead of galvanised components? |
Yes |
| Decisive factors for a drawer's durability |
How does the drawer meet all requirements for the durability of support rollers and runner rollers?
. By means of exceptionally wide rollers which increase the bearing surface, thereby reducing the surface pressure on the plastic sheathing?
. By means of 8 mm plastic-sheathed support rollers on the guiding rails?
. By means of 7 mm plastic-sheathed runner rollers on the drawers?
|
Yes

Yes |
|
| Has every effort been made in designing the drawer to make it impossible for drawers to run on the edges of the rollers only? In other words to prevent the support rollers from lying inclined to the running tracks of the drawer's lateral sections, or to prevent the runner rollers of the drawers from lying inclined to the running tracks of the guiding rails |
Yes |
|
| Do the support rollers have an axle stub with an exceptionally wide locating face to the guiding rail so that they held securely? |
Yes |
|
| Is the rivet head for securing the support roller to the guiding rail built up gradually, preventing cracks and weaknesses in the rivet head? |
Yes |
|
| Is double thickness of material used on the guiding rail in the area around the rivet joint, ensuring a secure fit? |
Yes |
|
| Does the guiding rail have moulded reinforcing beads in the area of the support rollers, providing greater rigidity? |
Yes |
|
| Do the special design and extra material used at the decisive points make the lateral section of the drawer so strong that it hardly bends at all when bearing a heavy weight, making it impossible for the drawer to run on the edges of the rollers only? |
Yes |
|
| Are the guiding rails held by three uprights so that they hardly bend at all when bearing a heavy weight, making it impossible for the drawer to run on the edges of the rollers only? |
Yes |
