Hammond HPBLG 30.5mm Pushbutton Steel Hole Plug, RAL7035 Light Gray

The Hammond HPBLG is an RAL7035 light gray steel hole plug sized for a standard pushbutton opening. The HP Series gives the standard pushbutton size as 30.5mm, and the ordering table lists this plug for holes up to 1.25 in (32 mm) in diameter. It is aimed at panel builders, OEM engineers and maintenance electricians who need to close off a pushbutton hole left empty after a control-panel change.

Made of steel and finished in RAL7035 light gray, the HPBLG is one of two colour options for this size; the same size in ANSI 61 gray is part number HPB. An oil resistant gasket seals the plug face, and a 10-24 x 0.55" threaded stud with a plated wing nut clamps it in place.

The plug diameter is 1.75 in (44 mm), and the part drawing shows a 1.76 in overall diameter along with 0.23 in and 0.79 in dimensions in its side and bottom views. Shipping weight is 0.13 lbs (0.06 kg), and it is listed in the Steel table of the HP Series ordering chart.

Steel HP Series hole plugs are a Recognized component UR & cUR for Type 1, 3, 3R, 4, 12 and 13, and are designed to seal against dust, oil and water. The HPBLG is listed as REACH and RoHS compliant, with UPC 623980412641.
