Forks that cannot enter the rack make every other specification irrelevant. Compare two-way and four-way fork entry, then confirm sleeve size, centers, forklift model, and aisle clearance before approving an Mgrack A-frame panel rack.

If an existing forklift cannot get its forks into the rack, the rack is not usable in that material flow. This is why a factory planning a double-sided A-frame glass rack should start with the forklift interface—not with a generic “standard fork pocket” assumption. The important questions are practical: which forklift model is already on site, what are the fork blade dimensions, and how much room is available for approach and turning?

Mgrack is a detachable, mobile panel storage and handling rack. Its A-frame geometry supports vertical storage of glass, stone, doors, or other panels, while the lower base can be configured around the planned handling method. The exact fork-entry direction, sleeve opening, and center spacing remain project details. They must be checked against the real equipment and the aisle, not selected from a universal catalogue value.

Two-way fork entry: a direct path for a defined material flow

Two-way entry means the forklift approaches the rack from the two planned ends or sides of the base. In the 15402 Mgrack design example, the rack is identified as 2000 × 1120 × 2100 mm, with double-sided fork entry, a top lifting plate, and an approximately 2000 kg unit capacity. That example is useful because it connects the rack layout to a real operating decision: if the forklift always approaches from the designated directions, a two-way base can avoid adding entry openings where the workshop does not need them. It can also keep the lower frame more focused on the intended load path. However, the example does not establish a universal Mgrack fork-pocket standard. The customer still needs to confirm the forklift approach direction, fork spacing, blade section, and turning envelope.

Four-way fork entry: more approach options, more interface checks

Four-way entry allows the forklift to engage the base from four directions. This can help when racks move between perpendicular aisles, loading zones, staging areas, and production cells. It does not automatically mean that every forklift can enter from every direction: sleeve openings, internal clearances, fork centers, wheel position, rack length, and turning space still control actual usability. Only some Mgrack designs include a two-way or four-way fork-entry arrangement, so four-way access must be specified and engineered for the project rather than treated as a default configuration. If the rack will also be pushed on casters, the team should separate the caster movement route from the loaded forklift route and confirm that the lower base does not create a collision point.

The 14629 A-frame door-loading example provides a concrete interface reference: the forklift sleeve outer dimensions are 200 × 80 mm and the center distance is 610 mm. These values belong to that 14629 project. They are not a standard fork-pocket size for all Mgrack racks, and they must not be copied into a new order without checking the buyer’s forklift. A rack with a different panel envelope, load distribution, or approach direction may require a different sleeve arrangement.

Match sleeve geometry to the forklift, then test the aisle movement

Fork entry is a three-dimensional fit. The sleeve opening must accept the fork blade with practical clearance, while the sleeve height and base rails must allow the forks to travel far enough under the load. The center distance must match the actual fork setting or the approved handling method. At the same time, the complete rack must be able to approach, lift, reverse, and turn without striking stored panels, columns, guards, or adjacent racks. Mgrack’s mobile A-frame format, caster base, lifting points, rubber contact protection, and ratchet tie-down options address different stages of internal handling; none of them removes the need for a site-specific forklift and aisle review.

What to confirm before selecting two-way or four-way entry

  • Forklift identity: Provide the make and model, rated capacity at the planned load center, fork blade width and thickness, usable fork length, and adjustable fork-center range. These inputs determine whether the 14629 reference of 200 × 80 mm sleeves and 610 mm centers is relevant—or must be redesigned.
  • Approach directions: Mark the actual loading and unloading sides on a simple floor plan. Choose two-way entry when the flow is controlled and repeatable; request four-way entry only when cross-aisle access has a clear operational benefit and the design can preserve the required base clearances.
  • Aisle and turning clearance: Measure the narrowest aisle, rack staging zone, door opening, column spacing, and turning area. A rack may accept the forks in a straight approach yet fail when the forklift must turn with the load. Confirm the full loaded height and sightline as well.
  • Load and protection conditions: State panel dimensions, unit weight, load distribution, lifting or tie-down method, rubber-contact requirements, and whether the rack is moved loaded or empty. Mgrack examples range from a 2000 kg double-sided design to other project-specific A-frame arrangements; capacity and interface must be quoted for the actual configuration.

Forks cannot enter the rack, or the turning aisle looks marginal? Send the forklift model, fork dimensions, sleeve preference, and available aisle width. GSR can review the approach direction and recommend a project-specific sleeve size and center distance for the Mgrack configuration.
