A pedalboard arrangement (600), including: a right support end (102); a left support end (104); a pair of support members (106) configured to support a foot pedal for musical effects, each secured in position between the right support end and the left support end, and each including a clip feature (110) that extends along a long axis (112) of a respective support member; and an attachment device (300) including: a clip (304) configured to clip onto the clip feature and remain retained thereon via a resilience of the clip at a variety of locations along the long axis; and a clip connector (306) including a clip hole (308) through a first end (310) configured to receive a fastener associated with the foot pedal and a second end (322) connected to the clip.

A fastening device for fastening a shielding part to a partnered fastening part, having: a sleeve with a through opening for a fastener; at least two bridging elements, which are equipped with outer regions in a radial direction for indirect or direct contact with the opposing outsides of the shielding part and are fastened to the sleeve with inner regions in the radial direction; a damping element is positioned between the bridging elements in an axial direction and outside of the sleeve in the radial direction, characterized in that the damping element is embodied as a spring element and has at least one spring arm, which is resiliently flexible in the radial direction and is equipped to cooperate in a supporting way with a hole rim of a hole of the shielding part.

A fastening assembly suitable for being fastened to a substrate with a front face and a first hole. The fastening assembly includes a fastening plate with a second plate with front and rear faces and pierced with a second hole aligned with the first hole. The fastening plate front face is fastened to the substrate rear face. The assembly includes a nut holder with a third plate with front and rear faces and pierced with a third hole aligned with the second hole and a nut fastened to the third plate on the side of the rear face and coaxial with the third hole. The front face of the nut holder is fastened to the rear face of the fastening plate. The fastening plate includes a first fastener that engages with a second fastener of the nut holder to removably fasten the nut holder to the fastening plate.

A latch assembly for a heating, ventilation, and/or air conditioning (HVAC) enclosure includes a latch having a securement portion configured to couple to an access panel of the enclosure and having a rotational portion. The rotational portion has an engagement feature configured to engage with a tool face or a tool receptacle and the rotational portion has a first retainer adjacent to the engagement feature. The rotational portion is configured to rotate relative to the securement portion such that a locking portion of the rotational portion transitions between a closed configuration and an open configuration. The latch assembly includes a handle accessory having a handle engagement driver configured to engage with the engagement feature of the rotational portion along a first linking axis and having a second retainer configured to couple with the first retainer of the rotational portion along a second linking axis, transverse to the first linking axis.

Disclosed is a tolerance compensator for joining materials that are spaced apart from one another. The tolerance compensator includes a base, a compensation member, a first flange portion, a first tree fastener, a second flange portion, and a second tree fastener. The compensation member is slidably engaged with the base and disposed at least partially within a cavity defined by the base. The first flange portion and the second flange portion are coupled to the base and extend radially outwardly from the base. The first tree fastener extends away from the first flange portion. The second tree fastener extends away from the second flange portion. Each of the first tree fastener and the second tree fastener include a body and a plurality of ribs extending outwardly therefrom.

An adjustable support system has a base bracket member, a clip member, and an outer bracket. The base bracket member has a first end wall that overlays a substrate, a body wall extending outwardly therefrom and a second end wall opposite the first end wall. The clip member has a base bracket member coupling, and a projecting arm. The base bracket member coupling is attached to the first end wall and overlies a portion of the body wall. The projecting arm is spaceable apart from the body wall. The outer bracket has a spanning wall with inner and outer sides. An outer end wall extends from the outer side. The spanning wall is slidably positionable between the body wall of the base bracket member and the at least one clip member, to sandwich the same. Wall assemblies and methods are likewise disclosed.

A method for mounting a stack of separating discs in a centrifugal separator bowl comprising a bowl body and a bowl hood includes mounting and securing the stack of separating discs on a distributor; placing and rotatably fixing the distributor in the bowl body; mounting the bowl hood on the bowl body; arranging a compression tool for compressing the stack of separating discs; fastening the screw with a second threaded end in a first (threading) of the distributor; tightening said nut, in relation to said first threaded end of said screw in such a manner that said distributor is lifted to an upper position; fixing the distributor in its upper position; and dismounting the compression tool.
