LOBSTER mungo quatro plug MQ-B

LOBSTER mungo quatro plug MQ-B

Strongest nylon plug of
the LOBSTER Mungo plug series.


・ For mounting equipment (washstand, illumination, air-conditioning equipment, kitchen equipment,
    saddle bands, ornament, etc.) to concrete and ALC.
・This nylon plug was developed to meet user needs for work rationalization by using a stronger nylon plug.
・With the 4-division structure, the area of adhesion to a boring surface is increased. Pull-out strength is
    considerably higher than that of conventional LOBSTER/Mungo nylon plugs.

[1] 4-division structure: The plug evenly fits in a prepared hole of a base material.
[2] Prevention of idle rotation: Projections at two points on the periphery grip the prepared hole securely,
       preventing idle rotation of the plug after insertion.
[3] Prevention of cave-in: The flange on the edge prevents a prepared hole from caving in
       when the plug is inserted.
[4] Prevention of early expansion: The internal special profile prevents and suppresses early expansion of
       the plug in a prepared hole during gauging work.
