## Abstract

Systems and methods of installing a fixture into a material are provided. The fixture includes a body and a cover assembly that is removably coupled to the body and configured to move relative to the body once the body has been secured within the material. The cover assembly includes a movable component configured to aid removal of the cover assembly.

## Claims

### Claim 1

A drain assembly comprising:
a coring sleeve including a stem and a bowl, the bowl extending radially outward and upward from the stem to define a bowl cavity; a drain received within the coring sleeve, the drain having a drain head received within the bowl cavity and a drain stem adjustably coupled to the coring sleeve stem; and
a cover assembly releasably coupled to the drain head and at least partially received within the bowl cavity, the cover assembly including a cover and a movable component received around a portion of the cover,
wherein the movable component comprises an annular ring having an inner ring and an outer ring spaced apart from the inner ring by ribs extending radially between the inner ring and the outer ring.

### Claim 2 (depends on 1)

The drain assembly of claim 1, wherein the ribs extend between the inner ring and the outer ring and define a pair of peripheral portions separated by an intermediate portion, the intermediate portion having a width that is larger than a width of at least one of the pair of peripheral portions.

### Claim 3 (depends on 1)

The drain assembly of claim 1, wherein the outer ring defines a discontinuity configured to allow the annular ring to collapse.

### Claim 4 (depends on 3)

The drain assembly of claim 3, wherein a radially outward extending projection is formed on the outer ring proximate the discontinuity in the outer ring.

### Claim 5 (depends on 3)

The drain assembly of claim 3, wherein the discontinuity is one or more notches formed in the outer ring.

### Claim 6 (depends on 3)

The drain assembly of claim 3, wherein the discontinuity is at least one of a gap within the outer ring or an extended section unsupported by a rib.

### Claim 7 (depends on 1)

The drain assembly of claim 1, wherein:
the cover includes a base section having a cylindrical outer surface and a raised section formed radially inward from the cylindrical outer surface and extending axially away from the base section; and
the annular ring is received around the raised section and rests upon the base section.

### Claim 8 (depends on 7)

The drain assembly of claim 7, wherein a plurality of notches are formed in the raised section and extend radially inward to receive tabs extending radially away from the annular ring.

### Claim 9 (depends on 7)

The drain assembly of claim 7, wherein a plurality of hooks extend away from the base section to engage the drain head.
